Deep below a desolate Utah mountain lies the largest platinum deposit ever discovered. A billion-dollar find, it waits for any company that can drill a world’s record, three-mile-deep mine shaft. EarthCore is the company with the technology, the resources and the guts to go after the mother lode. Young executive Connell Kirkland is the company’s driving force, pushing himself and those around him to uncover the massive treasure.

But at three miles below the surface, where the rocks are so hot they burn bare skin, something has been waiting for centuries. Waiting … and guarding. Kirkland and EarthCore are about to find out firsthand why this treasure has never been unearthed.

“From where I stand, Sigler is at the top of the tree.”
Jason Bradbury: BBC

“An exciting read, and very highly recommended for all science fiction enthusiasts, EarthCore would be a popular addition to community library SciFi collections and documents Scott Sigler as an effective, entertaining storyteller.”
Midwest Book Review

“This novel’s got it all: cutting-edge science; a perfectly-realized setting; terror both plausible and profoundly unsettling. EarthCore is more exciting than a thriller has any right to be!”
Lincoln Child: New York Times bestselling co-author of: The Book of the Dead, Relic, The Ice Limit and Death Match

“Bad things happen to bad people in this book. Then they happen some more. Very. Bad. Things. Things that make you wonder just what sort of childhood the author must have lived through. No way I’m going caving with him anytime soon. Or letting him near knives in my presence.”
Evo Terra: Founder of

“EarthCore is in-your-face, steel-tipped boot on your throat, speed-metal fiction. Nail-biting suspense and non-stop action breathe life into his debut novel.”
Tee Morris, co-author of “Podcasting for Dummies.”

“One thing I particularly like is that Sigler didn’t pull his punches or cop-out at any point. All the threats lined up at the beginning of the book were delivered on before the end. In fact I strongly recommend that you not get too attached to any characters as Sigler is ruthless at culling them throughout the novel.”
Eoghann Irving: Solar Flare

“There’s a lot to recommend this book, and anyone who enjoys sf thrillers will enjoy this.”
Steve Mazey: EternalNight

“EarthCore may be considered a sci-fi novel, but I would rate it right up there with some of my favorite creepy horror novels. EarthCore is a fantastic choice to add to your bookshelf.” Tracy Farnsworth: Roundtable Reviews

“I loved this book! Right from the start it built the tension and had me wondering ‘What the heck is it?’ Then, after the reveal it had me squirming in my chair going “Oh my God! EEK!!”
Melanie Gilbreath: Coffee Time Romance

    Wow, all prints have been gathered and destroyed?

    That makes my first print, dedicated and signed copy worth some serious bucks!

    But I wouldn’t sell it for the world!

    Keep up the good work Scott, can’t wait for Earthcore 2!

      @Marios: Well, scarcity is what makes the price so high, and you holding onto yours is part of the master plan. Although, I get no money out of this master plan, so, there you go. Glad you like it!

    Well I look forward to that re-release. I just finished and loved the podcast and told several non-audiobook friends about it.

      @No JacqiB: Because we had to buy up the print copies that were not yet sold and destroy them as part of our five-book deal with Crown Publishing. Crown wanted all the rights to All Things Sigler and didn’t want competition in the marketplace.

      We do plan on re-publishing it in the near future, but can’t say exactly when.
