Book cover of The Cosmic Serpent

Martin Sweatman Author Of Prehistory Decoded

From my list on coherent catastrophism.

Why am I passionate about this?

I have always been interested in the world’s mysteries. This is why I studied theoretical physics. Ultimately, this scientific pathway led to a permanent position in the School of Engineering at the University of Edinburgh. But archaeology is also fascinating, and I was lucky enough to decode some ancient symbols at one of the world’s most important archaeological sites, Göbekli Tepe. The resulting story combines archaeology, astronomy and geophysics to present a new synthesis for the origin of civilization. My academic background in science has helped me to provide compelling evidence and arguments for these ideas.

Martin's book list on coherent catastrophism

Martin Sweatman Why Martin loves this book

This book trail-blazed the new scientific discipline of coherent catastrophism back in 1982. Based on ideas in a couple of their earlier academic papers, Profs. Clube and Napier make the case for an important new class of cosmic impact event, one caused by fragmenting comets trapped within the inner solar system.

I found the book to be essential reading to understand how such events can occur and how they have hitherto been largely overlooked by science. It introduced me to a fascinating new view of the solar system. I also found it interesting to see how, in the intervening 40 years, the author’s scientific arguments and predictions are mostly borne out, especially by the Younger Dryas impact, circa 10,850 BC.

Martin's book list on coherent catastrophism

Martin Sweatman Why Martin loves this book

This book continues where Cosmic Serpent left off. It’s the New Testament to The Cosmic Serpent’s old one. Published 8 years after the former, it provides even more details on the cometary astronomy of coherent catastrophism along with a healthy dollop of ancient history.

Just like The Cosmic Serpent, I found this book to be essential reading for the coherent catastrophism enthusiast. Indeed, their books are highly prescient, being published long before the Younger Dryas impact became such a hot topic. In my view, Clube and Napier deserve a Nobel Prize.

What is this book about?

During five days in late June 1975, a swarm of boulders the size of motor cars struck the moon at a speed of 67,000 miles per hour. On 30 June 1908 an object crashed on Siberia with the force of a large hydrogen bomb. The moon was also struck on 25 June 1178 struck, this time by a missile whose energy was ten times that of the combined nuclear arsenals of the world. Why late June? What is the nature of such events? And what threat do they pose to mankind? The authors aim to reveal the answers in this…

Martin's book list on coherent catastrophism

Martin Sweatman Why Martin loves this book

This is a great introduction to the science of the Younger Dryas impact. Published a year before the seminal paper of Firestone et al. (2007), it makes the case for a devastating cosmic event, probably a meteor or comet impact, circa 10850 BC.

The book combines science with historical accounts and mythology to arrive at this stunning conclusion. Although I think some of the evidence in the book is speculative and possibly wrong, I think their main arguments in 2006 have held up well to intense scrutiny by critics since then. I consider this book to be another essential read for the coherent catastrophist enthusiast.

Martin's book list on coherent catastrophism

Martin Sweatman Why Martin loves this book

Prof Mike Baillie presents a fascinating account of how ancient comet impacts, largely a result of coherent catastrophism, might have altered the course of history. Baillie, an eminent dendrochronologist, argues how comets and their impacts might have been instrumental in forming ancient myths and religions across the world.

Even though the examples he provides a far from watertight, I consider his general viewpoint almost certainly correct. And that makes this another essential read for the coherent catastrophist enthusiast.

1 author picked Exodus to Arthur as one of their favorite books, and they share why you should read it.

What is this book about?

Professor Mike Baillie argues that the Earth has undergone several catastrophic encounters with comets, or their debris, over the last five thousand years, and that these cosmic devastations are accurately preserved in Old Testament and Chinese texts, and in many myths and legends across the world. This extraordinary scenario is based on the scientific analysis of ancient tree-ring patterns.
It is only now, with the firm chronological framework provided by the tree rings, that the story can be put together. There is no doubt that the story is surprising. However, it would be easier to believe that the account in…


Book cover of Theory of the Earth Volume I

Alexandra Witze Author Of Island on Fire: The extraordinary story of Laki, the volcano that turned eighteenth-century Europe dark

From my list on on deep time.

Why am I passionate about this?

I’m a science journalist in Colorado, living in the foothills of the Rocky Mountains that were raised by millions of years of mountain-building. I studied geology in college and now write about the earth and space sciences, primarily for the journal Nature. On reporting trips I’ve camped on floating Arctic sea ice and visited earthquake-ravaged mountains in Sichuan, China. But my favorite journey into deep time — the planet’s unfathomably long geologic history, as preserved in rocks — will always be a raft trip with scientists along a section of the Colorado River in Arizona.  

Alexandra's book list on on deep time

Alexandra Witze Why Alexandra loves this book

This is the classic book on the deep history of the Earth. Hutton is known as the father of modern geology, because he understood that today’s rocks represent the accumulation of changes over incredibly long geologic epochs. In publishing his ideas he went against the then-popular notion of catastrophism, which held that sudden, violent events such as floods had shaped most of the Earth’s surface. Hutton instead argued for slow changes over time — a concept known as uniformitarianism — and, crucially, recognized that two rock types at Siccar Point, Scotland, had formed at different times separated by many millions of years. “The mind seemed to grow giddy by looking so far into the abyss of time,” one of Hutton’s companions said. That realization set the stage for future scientists to explore the ramifications of a deep geologic past.

Book cover of UnHappenings

Larry A. Brown Author Of Temporal Gambit

From my list on time travel resulting in alternate realities.

Why am I passionate about this?

I have read SF, starting with the classic Jules Verne, since I was a young teenager. Soon I discovered Bradbury, Asimov, Clarke, Ellison, Zelazny, Dick, all of whom lit up my mind with wondrous and sometimes dangerous visions of possible futures. During the COVID shutdown period, when our university went to online instruction, my wife convinced me to try my hand at writing in my favorite genre. Previously I had written a textbook, How Films Tell Stories (listed here at Shepherd), but never any fiction, so I wrote Temporal Gambit, a time-travel adventure combined with themes of first contact, artificial intelligence, and alternate history. I then followed it with a sequel. I hope you enjoy. 

Larry's book list on time travel resulting in alternate realities

Larry A. Brown Why Larry loves this book

One of the best SF novels I’ve read in the last 25 years.

The story takes you on a journey through multiple, shifting realities as different time travelers compete to change history to their advantage without wiping out everything and everyone they know and love.

Unlike so many books these days, this one never drags or bores with unnecessary background details but keeps moving from one catastrophic change to another. Highly recommended.

As with my other recommendations, I am making this one based on the impact the book had on me. From this novel, as well as the others that Jerry wrote, I learned how important it is to build a comprehensive world-universe when planning a book. And, when I sat down to pen the first book in what would become the Legion of the Damned series, I attempted to build a reality as fully realized as the CoDominium universe is.

Book cover of My Friend Earth

Mimi Chao Author Of Let's Go Explore

From my list on picture books to inspire mindful curiosity in kids (and adults).

Why am I passionate about this?

I believe that creativity and mindfulness are critical qualities for a well-lived life. This is something I learned through personal experience as a former lawyer who returned to my childhood dream of creating art and stories. Mindfulness—a kind, nonjudgmental awareness of what is happening in the present moment in and around you—helps people of all ages practice self-compassion, appreciate the world and others, and see life as an adventure. I write and illustrate picture books to share these concepts through storytelling, teach mindful creative classes, and am a certified meditation teacher through The Awareness Training Institute and the Greater Good Science Center at UC Berkeley.

Mimi Chao Why Mimi loves this book

I love the beautiful illustrations in this picture book about mother nature. The artwork lends itself to mindful observation of our wonderful earth and appreciation for the environment without being pedantic, showing rather than telling.

The pages also feature creative interactive elements like cutouts and flaps that create an experience of exploration and discovery for young readers. I’ve found that there are not too many mindfulness picture books with really gorgeous art, and this is one of them.

Book cover of Chocky

R.E. Palmer Author Of Song of Echoes

From my list on sci-fi you’ll have to prise from my dead hands.

Why am I passionate about this?

From as early as I can remember, I've been fascinated by science and the supernatural. I guess it was the bookcases of my parents and relatives that stoked my imagination as a child. From books about mysteries of the universe, to stories of fairies, nymphs and banshees, all asked questions that I longed to know the answers to. It’s a habit I've maintained throughout my life, always investigating, always challenging my beliefs. I like to think this has given me the skills to write a good, fantasy story. While I create worlds, characters, and rules of magic based on a logic that’s believable, as the world my characters live in is very real to them.

R.E.'s book list on sci-fi you’ll have to prise from my dead hands

R.E. Palmer Why R.E. loves this book

I first read Wyndham when staying at my grandmothers aged eleven during a long summer holiday. I devoured the books left there by my uncle, and Chocky was the one that ‘blew my mind’. The main character was a similar age to me at the time, and the thought that an alien could inhabit his mind was both scary and fascinating. I imagined what I would do if an alien had chosen me, and what I would do with the superpowers it might bring. I was halfway through writing my first book in 2010 when I suddenly realised it was this book that provided the inspiration—now that’s a sign of a good book. I re-read Chocky for the first time last year and found it evoked the memories of my late grandmother and my summers back in the 70s.

Matthew, they thought, was just going through a phase of talking to himself. And, like many parents, they waited for him to get over it, but it started to get worse. Mathew's conversations with himself grew more and more intense - it was like listening to one end of a telephone conversation while someone argued, cajoled and reasoned with another person you couldn't hear. Then Matthew started doing things he couldn't do before, like counting in binary-code mathematics. So he told them about Chocky - the person who lived in his head.

Book cover of The Paths Between Worlds

M.G. Herron Author Of The Auriga Project

From my list on fantasy with unusual portals to other worlds.

Why am I passionate about this?

Is there any genre so purely escapist as a portal fantasy adventure? I grew up on stories like these, devouring any book I could find that had a portal in it, from Alice in Wonderland to The Chronicles of Narnia to Tunnel in the Sky. Books, in a way, are portals to other places and times, and as a child I wandered through the stacks of the local library, plumbing the depths of every strange world I could get my hands on. If you want to experience the long-lost thrill of falling into a story, few do it like those that take their characters through portals to other worlds.

M.G.'s book list on fantasy with unusual portals to other worlds

M.G. Herron Why M.G. loves this book

The doorway in this novel is a departure from the usual.

And though it is unusual, yet it ties to humankind's fascination with portals.

The first portal in storytelling history, really, is the threshold a person must pass through to get from life to death.

That threshold has been epitomized in mythology as long as human beings have been using stories to explain the strangeness of existence.

In this sci-fi story, death is once again the portal between worlds. What would you do if, right before you died, an alien entity asks if you’d like to be saved?

Would you do it?
