Book cover of Nophek Gloss

Rohan Oduill Author Of Cold Rising

From my list on science fiction books with working class heroes.

Why am I passionate about this?

Having spent thirty years working as a chef, I was always going to have working-class heroes in my stories. When someone said this is uncommon in science fiction, I didn’t believe them. But then I couldn’t think of any. I started searching through my bookshelves, and still, I couldn’t find enough to fill this list. I asked on socials and eventually found five books. 

It would seem natural that in a science fiction world of adventure and exploration, the professionals would be at the forefront. But I am pretty sure that the toilet cleaners on the Death Star would still have a story or two to tell.

Rohan's book list on science fiction books with working class heroes

Rohan Oduill Why Rohan loves this book

It became obvious to me early in this book that Nophek Gloss was written by someone who works with their hands. Not only in how the action was choreographed but also in how the world was described.

This brings a real world feel to the writing as we join Caiden helping his father with the menial tasks that keep a farming community running. Soon after, his whole world is destroyed. But as Caiden escapes and throws in with a ragtag bunch of aliens and a ship with a conscience, we can appreciate his point of view as someone who has seen so little of the universe but is suddenly exposed to multitudes of new and unusual things as he adventures into the unknown.

This book is for sci-fi fans who enjoy great worldbuilding, interesting aliens, and action throughout.

Book cover of Between Two Fires

Rob Samborn Author Of The Swordsman of Venice

From my list on epic historical adventure novels.

Why am I passionate about this?

I’ve been fascinated with history and adventure for as long as I can remember. Nothing thrills me more than an epic quest, particularly if the hero is flawed. As an author of historical fiction, I’ve read countless books and spent thousands of hours researching topics and places, from South America to Europe to Asia. I hope you enjoy these epic historical adventures as much as I have! If you have recommendations of your own, please share!

Rob's book list on epic historical adventure novels

Rob Samborn Why Rob loves this book

The only fantasy book on this list, Between Two Fires, is one of the most haunting and original novels I've ever read.

Set in plague-ravaged medieval France, it blends historical fiction, horror, and dark fantasy into a story that’s both epic and deeply personal. What stayed with me most was the unsettling atmosphere. Every ruined village, abandoned cathedral, and lonely stretch of road carries an almost unbearable sense of dread.

Yet amid the horrors, Christopher Buehlman crafts characters whose courage, sacrifice, and humanity shine through the darkness. The supernatural encounters are genuinely terrifying, but they're balanced by moments of hope, redemption, and surprising tenderness, all set against a backdrop of real historical events.

It's a novel that challenged, unsettled, and captivated me from beginning to end, and long after I finished the final page, I found myself still thinking about its unforgettable journey.

13 authors picked Between Two Fires as one of their favorite books, and they share why you should read it.

What is this book about?

His extraordinary debut, Those Across the River, was hailed as “genre-bending Southern horror” (California Literary Review), “graceful [and] horrific” (Patricia Briggs). Now Christopher Buehlman invites readers into an even darker age—one of temptation and corruption, of war in heaven, and of hell on earth… And Lucifer said: “Let us rise against Him now in all our numbers, and pull the walls of heaven down…” The year is 1348. Thomas, a disgraced knight, has found a young girl alone in a dead Norman village. An orphan of the Black Death, and an almost unnerving picture of innocence, she tells Thomas that…

Scott Drakeford Why Scott loves this book

This book is still quite under the radar, but it will get it's due someday, I think.

Wen Alder is a top student in the new and growing empire before being radicalized by his magic-practicing rebel of a grandmother. It’s fresh and familiar all at once. Inspired by Taiwanese history, this book will not disappoint those looking for elegance and creativity in a classic story of revolution and fighting back against an aggressive empire.

Book cover of 36 Streets

D.P. Vaughan Author Of Ethereal Malignance

From my list on complex identities.

Why am I passionate about this?

From a young age, I've been engrossed by the complexities of identity, a theme I explore as an Australian speculative fiction writer. My own identity comes with its quirks—I hold a Bachelor of Music in Composition, spent a decade in admin roles, and the better part of another decade teaching English to adult migrants, refugees, and asylum seekers. This eclectic background enriches my narratives, which blend supernatural elements with grounded realism and diverse representation. Whether it's exploring loneliness or delving into the lives of victims of bullying, my unique lens makes me well-suited to recommend books that tackle intricate themes of identity.

D.P.'s book list on complex identities

D.P. Vaughan Why D.P. loves this book

36 Streets by Australian author T.R. Napper is a cyberpunk thriller set in a futuristic noir Vietnam that tackles identity in a unique way.

The protagonist, a woman born in Vietnam but raised in Australia, grapples with her sense of belonging—deported from her adopted country due to racist government policies, her body language and command of English is as an Australian, and she is painfully aware that her Vietnamese is heavily accented and uncertain, and that her body language doesn’t match the locals of her birth nation.

Add to that the ability to edit human memory and to experience VR so realistically that you can live as someone else, and you have a story that questions the very fabric of identity.

Book cover of The Dark Highlander

L. S. Bethel Author Of The King's Seer

From my list on romance with supernatural worldbuilding.

Why am I passionate about this?

Give me all the supernatural and fantasy intrigue with love on the side. Sometimes this world of ours is too much to deal with and it’s nice to visit other worlds. To read and write about the justice, love, and magic of other things that may be lacking in your life can be cathartic and gives us something to look forward to and strive for. While some of the more supernatural aspects might be out of reach, the beauty of unbreakable bonds forged in love and trust, people willing to sacrifice for what they believe in, and seeing justice prevail also gives me the hope that it's not unreachable if you believe it. 

L. S.'s book list on romance with supernatural worldbuilding

L. S. Bethel Why L. S. loves this book

For my bookworm girlies who long for a historical adventure. This was one of the first historical fantasy/romance books I ever read and I loved it. I remember really loving the main character because not only was she bookish and unintentionally funny, she was smart, awkward, and relatable. The story gives the reader a chance to dive into a culture you may not be completely familiar with and that accounts for half the intrigue right there! I love the lore, the supernatural elements, the history, the action. It’s a story that ticks all the boxes for fun reads and I’d encourage anyone who enjoys those things to give it a shot.

Book cover of The Saint of Bright Doors

J.T. Greathouse Author Of The Hand of the Sun King

From my list on fantasy with wonderful characters and settings.

Why am I passionate about this?

I firmly believe that literature exists to do more than entertain us. It has an incredible power to expand our perspective about the world and the lives of the people around us. Fantasy, in particular, can stretch the mind’s boundaries by asking us to empathize with compelling characters and wrap our heads around strange and wondrous worlds. I try to achieve that in my books, presenting thrilling stories, fantastic worlds, and emotionally charged moments, but always through the eyes of real-feeling people. I hope the books on this list will feel as mind-expanding and empathy-building to you as they did to me!

J.T.'s book list on fantasy with wonderful characters and settings

J.T. Greathouse Why J.T. loves this book

My appreciation for this book snuck up on me. I thoroughly enjoyed the first third or so, in which we are introduced to Fetter–destined to assassinate his godlike father–and are introduced to the fascinating city in which the story is set. But I wasn’t as enthralled with what I took, at the time, for a bit of a meandering middle section. However, the utterly creative and mind-twisting final fifth of the book won me back over.

With time, I’ve come to appreciate the subtle thematic and character work in those middle chapters. Of all the books on this list, this one pushes the boundaries of fantasy the most, both in worldbuilding and characterization, but it’s a masterclass in both, and I hope it has a massive impact on the genre going forward.

5 authors picked The Saint of Bright Doors as one of their favorite books, and they share why you should read it.

What is this book about?

The Saint of Bright Doors sets the high drama of divine revolutionaries and transcendent cults against the mundane struggles of modern life, resulting in a novel that is revelatory and resonant.

Fetter was raised to kill, honed as a knife to cut down his sainted father. This gave him plenty to talk about in therapy.

He walked among invisible powers: devils and anti-gods that mock the mortal form. He learned a lethal catechism, lost his shadow, and gained a habit for secrecy. After a blood-soaked childhood, Fetter escaped his rural hometown for the big city, and fell into a broader…

Deb E. Howell Author Of Healer's Touch

From my list on fantasy series with powerful worldbuilding.

Why am I passionate about this?

I grew up reading The Brothers Grimm, Enid Blyton, and any number of stories that would come under the Fantasy umbrella. Later on, I fell in love with Garion and his friends in The Belgariad and The Malloreon. Later, I delved into the literature and Science Fiction of Iain (M.) Banks, and latched onto Terry Pratchett’s Death to navigate the vast Discworld series. I find I always return to Fantasy, and seek to come away from a book feeling as though I’ve made friends within the pages. This, too, was my goal when I took up writing.

Deb's book list on fantasy series with powerful worldbuilding

Deb E. Howell Why Deb loves this book

I read this before I read the preceding trilogy: Phèdre’s Trilogy, and was well drawn in without the background knowledge that may have come from reading the two series in order. I later did read Phèdre’s Trilogy and enjoyed it, but it was Imriel’s Trilogy that really captured me. I love that while most Fantasy series will focus on aggressive politics and war, these series are more about the arts and diplomacy and humans being very human in all their facets. Imriel was a captivating character who I was eager to follow along with as I discovered the world he lived in.

Ronald A. Geobey Author Of Gods of Kiranis

From my list on sci-fi fantasy novels for immersive worldbuilding.

Why am I passionate about this?

While Dune, Star Wars, Battlestar Galactica (1980s), and other SF staples laid the foundation for my love of SFF, I was also reading about the universe from a young age. Along came Star Trek: The Next Generation in the ‘90s and the stage was set. Completing Bachelor’s Degrees in Ancient History & Archaeology; Religions & Theology; and a PhD in Near and Middle Eastern Studies copper-fastened my passion for the ancient world and the history of religion, and along with reading historical fiction and fantasy, everything merged into the almost allegorical universe you’ll find in Kiranis. Lovers of all the above will find something here.

Ronald A. Geobey Why Ronald loves this book

I discovered the Pearl Saga (a trilogy) via Van Lustbader taking up the reins on Robert Ludlum’s Bourne novels. While I was reading these books, I was waiting to hear from Voyager (Harper Collins) regarding an epic fantasy novel I wrote, which featured in its climactic scenes a girl using crystals to trap a dragon in a cage-like device inside a mountain. There was a delay in the publication of the third book of the Pearl Saga, and when it came out, it featured a girl holding a ‘crystal’ before a dragon, and it was called The Cage of Nine Banestones. My heart sank, but it turned out that the delay was related to the death of Van Lustbader’s father.

The trilogy begun in ‘Ring’ is for some brooding and self-indulgent, but for me it was a triumph of worldbuilding and alien realia, with technology and sorcery vying…

Paula Altenburg Author Of The Rancher Takes a Family

From my list on featuring worldbuilding as part of the story.

Why am I passionate about this?

I’m a writer. I also teach plot through non-credit university workshops and writer groups, and the one thing I stress is that storytelling is about reader experience. Worlds are a huge part of that experience. A degree in social anthropology makes me very conscious of the way my characters interact with their worlds. My fictional cowboys currently reside in Montana. But what if I wanted to move my cowboys to Manhattan? That requires a whole different story world—one my characters may or may not be comfortable in. My readers would now have to buy into the change in location. See the effect the world has on the story?

Paula's book list on featuring worldbuilding as part of the story

Paula Altenburg Why Paula loves this book

Madeline Hunter is the pseudonym of an art historian who teaches at the university level, and that expert knowledge translates well in her books.

The little bits and pieces of art detail she adds to her story worlds really bring them to life. There’s also an element of mystery that deepens the plot. The Seducer is the first book in The Seducer series, and while it’s not the first of her books that I’ve read, the story of Diane Albret and Daniel St. John is the one that made me a fan.

The heroine is a recent boarding school graduate, and the hero is her far more experienced guardian. In the modern-day world, this premise is all kinds of creepy. The power dynamics between this couple were so far off, I wasn’t sure how Hunter could make this a romance.

But based on the historical details built into the world,…

This story was interesting in the way that the author had two main characters who were twins with widely different roles.
