Book cover of A Short History of Nearly Everything

Iris Gottlieb Author Of Trash Talk: An Eye-Opening Exploration of Our Planet's Dirtiest Problem

From my list on the mysteries of nature.

Why am I passionate about this?

I have been intrigued by the stranger, lesser-known parts of the natural world for as long as I can remember and have been continuing to explore those themes in my own work. I love that humans haven’t learned all there is to know about the natural forces that have ruled this planet for longer than we’ve been here. I enjoy books that peel back a layer into these mysteries by writers who have an appreciation for their existence, their ingenuity, and their importance. I have dedicated much of my career to synthesizing big topics into accessible, engaging, and fun information that creates curiosity and a desire to understand the world around us. 

Iris' book list on the mysteries of nature

Iris Gottlieb Why Iris loves this book

I find great pleasure in learning a little bit about a lot of things, and this book scratches that itch in a great way. Touring through big scientific concepts, Bryson delivers the potentially overwhelming (and boring) information in a fun way that made me understand space-time way more than any middle school physics class did.

It’s not a book that needs to be read in order or even be read in its entirety to enjoy, so it’s fun to have around to pick up a chapter here and there or read it straight through. The other day I went back and referred to it while having a conversation about space time and found an explanation that we both understood—and enjoyed.

It is April 1st, 2038. Day 60 of China's blockade of the rebel island of Taiwan.

Book cover of The Hitchhiker's Guide to the Galaxy

L.N. Hunter Author Of The Feather and the Lamp

From my list on humorous fantasy and science fiction.

Why am I passionate about this?

Growing up at a time when both Monty Python and ‘alternative comedians’ like Ben Elton were on the telly, I couldn’t help but absorb British humor, and coupling that with a love of science fiction and fantasy (Asimov, Heinlein, Moorcock, etc.), I was ripe for an introduction to Douglas Adams and Terry Pratchett… And the rest is history. The world is too serious a place, and I find comedy of all kinds, but especially SFF, a welcome escape. My own writing has been inspired by all the books on this list, and while I work in a range of genres, almost everything includes at least some snarky humor.

L.N.'s book list on humorous fantasy and science fiction

L.N. Hunter Why L.N. loves this book

I first encountered Douglas Adams when I caught The Hitchhiker’s Guide on late-night radio, and I was hooked. The novel is slightly different, with Adams giving a bit more consideration to plot and logic, but it has the same wonderful, rapid-fire dialogue style, which has seldom been replicated.

I absolutely love Arthur Dent’s ludicrous accidental odyssey, meeting characters like Zaphod Beeblebrox and the wonderfully named Slartibartfast. The Guide sits in the background, popping up to provide superbly funny explanations of the history of the universe, humanity’s obsession with money, and a lot more.

For me, the thing that sets this apart from a lot of SFF humor is its ‘Britishness’—there’s a distinct feel of the surreal comic legacy of, for example, Monty Python and The Goon Show.

Book cover of Fuzz: When Nature Breaks the Law

Ginjer L. Clarke Author Of Animal Allies: Creatures Working Together

From my list on nonfiction about fascinating animal behavior.

Why am I passionate about this?

I’m secretly eight years old inside. I love fascinating animal and science stuff, especially cool, weird, and gross facts. Readers of my children’s books see this passion in action. My best-selling and award-winning nonfiction animal books have sold more than 3 million copies worldwide since 2000. I focus particularly on reaching reluctant, struggling, and English-language-learning readers by packing my books with lots of action and high-interest topics to keep them turning pages. I’m recommending these top-five narrative nonfiction animal books for adults because these authors have influenced my research and thinking—and because they’re terrific stories!

Ginjer's book list on nonfiction about fascinating animal behavior

Ginjer L. Clarke Why Ginjer loves this book

After hearing Mary Roach describe research for this book during an NPR interview, I couldn’t wait to hear more of her bizarre, funny, sometimes unbelievable stories about animals “breaking the law.”

These are human laws, of course, that animals are heedless of and not bound by; however, human-animal conflicts are on the rise, and we must be aware of how to lessen negative interactions as we continue to move into territory where animals previously roamed freely. Humans are more often the problem in these encounters, but we can provide solutions too.

A must-read for all who love wildlife and spend time in nature!

By Mary Roach ,

Why should I read it?

7 authors picked Fuzz as one of their favorite books, and they share why you should read it.

What is this book about?

What's to be done about a jaywalking moose? A bear caught breaking and entering? A murderous tree? Three hundred years ago, animals that broke the law would be assigned legal representation and put on trial. These days, as New York Times best-selling author Mary Roach discovers, the answers are best found not in jurisprudence but in science: the curious science of human-wildlife conflict, a discipline at the crossroads of human behavior and wildlife biology.

Roach tags along with animal-attack forensics investigators, human-elephant conflict specialists, bear managers, and "danger tree" faller blasters. Intrepid as ever, she travels from leopard-terrorized hamlets in…

Book cover of The Thursday Murder Club

Alexandra Addams Author Of The Self-Made Saint

From my list on menopause as a superpower for women who are happy to jump off the rollercoaster of youth.

Why am I passionate about this?

I started my motherhood journey when I was barely out of my teens. For the next two decades, I only knew myself as a wife and mother. As my brood of five children grew into adults, I found myself poorly equipped to parent independent Gen X and Z’ers. Then, at 46 years of age, when perimenopause hit me like a hurricane, I found myself evolving into another woman altogether. The good news was – I really liked her! I hope you enjoy these books about mid-life women parenting adult children and rediscovering themselves in the never-ever-done-aftermath of motherhood.

Book cover of Extreme Ownership: How U.S. Navy Seals Lead and Win

Scott Greenberg Author Of Stop the Shift Show: How to Turn Your Struggling Hourly Workers Into a Top-Performing Team

From my list on managing employees and building teams.

Why am I passionate about this?

I’m fascinated with the relationship between personal growth and professional performance. Why is it in the same environment, doing the same work, some people can excel while others struggle? Most chalk it up to external circumstances that can’t be controlled. Others focus on tactics. But I’ve learned top-performers are masters at the human side of their work–the way they think, lead and serve–and that’s what gives them their edge. All of my work centers around infusing hard skills with improved soft skills, and getting better results in the process. That’s the stuff I find delicious, and it’s what I speak and write about.

Scott's book list on managing employees and building teams

Scott Greenberg Why Scott loves this book

I like tools and tactics, but when reading, I also like engaging stories. This book is loaded with them, offering a raw and authentic approach to leadership.

I liked how Willink and Babin pull valuable business takeaways from intense experiences on the battlefield. And I liked that a major takeaway is the importance of accepting absolute responsibility for what you do. No one’s going to argue with these guys.

I found the book totally empowering.

Highly decorated Navy SEALs, now successful businessmen, show readers how to lead and win in business and in life with principles learned on the battlefield.

With riveting first-hand accounts of making high-pressure decisions as Navy SEAL battlefield leaders, this book is equally gripping for leaders who seek to dominate other arenas. Jocko and Leif served together in SEAL Task Unit Bruiser, the most highly decorated Special Operations unit from the war in Iraq. Their efforts contributed to the…

K.T. Lee Author Of A Nose for Mischief

From my list on readers who love science, dogs, and crime fighting.

Why am I passionate about this?

I love great storytelling, whether it’s in the form of a great mystery, romance, science fiction/fantasy, or non-fiction. I even love a story well told through the medium of television (I see you, The Good Place!). The books on this list are books I’ve read and loved and/or used as research to write my own series of dog-based cozy mysteries.

K.T. Lee Why K.T. loves this book

A book about dogs who help protect soldiers had my attention before I even cracked it open. Soldier Dogs is exactly as advertised—Goodavage details how dogs are trained, the bonds that handlers form with their canine partners, and some of the challenges associated with the difficult job these dogs do. This book was an interesting and informative read for anyone curious about the lives of working K-9s and their handlers.

Book cover of Ada's Algorithm: How Lord Byron's Daughter Ada Lovelace Launched the Digital Age

I read and write lots and love doing so. So when I need a break, the last thing I want is another book, right? Wrong! I take a break with books, and I love fun books that are an escape from the normal day-to-day, ones that won’t lull you to sleep, ones that end too quickly. It’s a sickness, I know, and I’ll deal with it as soon as I have worked through this pile of books on my desk.

Ben's book list on when you really need to get away, without actually getting away

Ben Forta Why Ben loves this book

I’m a geek; I’m ok with that, and I fully embrace that reality. I love books that tell the stories of the early pioneers who brought about computing as we know it. And few figures are as important and underappreciated as Lady Ava Lovelace.

She literally created what we now call “computer programming languages” before there were modern computers and electricity was widely available! Oh, and she did this before she died at age 33. This is a feel-good, inspiring tale of a woman well ahead of her time.

1 author picked Ada's Algorithm as one of their favorite books, and they share why you should read it.

What is this book about?

“[Ada Lovelace], like Steve Jobs, stands at the intersection of arts and technology."—Walter Isaacson, author of The Innovators

Over 150 years after her death, a widely-used scientific computer program was named “Ada,” after Ada Lovelace, the only legitimate daughter of the eighteenth century’s version of a rock star, Lord Byron. Why?

Because, after computer pioneers such as Alan Turing began to rediscover her, it slowly became apparent that she had been a key but overlooked figure in the invention of the computer.

In Ada Lovelace, James Essinger makes the case that the computer age could have started two centuries ago…

I’m a huge Michael Crichton fan, you know, the guy who wrote Jurassic Park. He actually wrote lots of other books, every one a masterpiece, but this may be my favorite (and it’s hard to pick a favorite Chrichton, I am second guessing myself as I wrote this!).

In this book, one of his longest, Crichton tackles climate change, and no, don’t roll your eyes, this is a face paced thriller that will have you struggling to discern science from fiction.

Why am I passionate about this?

I draw and write the Sketchplanations newsletter, in which I'm slowly explaining the world, one sketch at a time. In it, I blend my training as a designer and entrepreneur, what I learned in my PhD at UC Berkeley, and my amateur love of sketching, and I try to share my personal lightbulb moments through simple sketches. I'm constantly looking for ideas that change how I look at the world and myself. The books here are some of those that have given me the most valuable ideas I want to share and entertained me along the way.

Jono Hey Why Jono loves this book

Randall Munroe brings a magic combination of impressive science and fun cartoons that make me laugh. I found this book great fun throughout.

As I read Randall's absurd methods of solving problems—for example, literally moving a house by lifting it with multiple helicopters —I also have a sense that I'm actually learning, if not helpful science exactly, at least intelligent ways of thinking about problems.

Munroe had a job building robots at NASA—reading the book, you can tell he's a brilliant guy—and his charming and disarming distinctive stick men picture style keeps things fun all the way through.

Matthew J. Kushin Author Of Beware The Smart Kids

From my list on YA male protagonists that you wish you knew IRL.

Why am I passionate about this?

I’m a professor and YA author. Books helped me navigate the difficult choices I faced growing up. I gravitated to characters that I could picture myself befriending and looking up to because they had the bravery and strength that I wanted to have. As an author, I believe we need more stories about people who leave a positive mark on the world. I try to write characters that I can both relate to and would want to be friends with: characters who, in facing difficulty, discover the strength of their humanity because they have a light and goodness that shines somewhere deep inside.

Billy is facing a test of loyalty in his search for his identity. Will he be the person his friends want him to be? Who does he want to be? He’s done his fair share of boneheaded things. But he’s also got a good heart buried somewhere in there. And I’m rooting for him.
