Earthcore was published in 2005 from Dragon Moon Press, the publisher of great authors like Tee Morris and Jana Oliver. In 2007, Crown Publishing bought the rights to Earthcore, and we hope to give it a great edit, then re-publish it in 2009 or 2010. I’m fired up for the chance to take another stab at Earthcore, as it was the my first novel and I think I can knock it out of the park with another rewrite.


You can buy Earthcore at and sometimes copies are available on eBay – but watch out, they are pricey!

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: Host of XM Satellite and FM syndicated radio show “The Dragon Page.”

"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

    This might be an obscure reference but these aren’t as cool as the “Rare Butt Hole Eatting Scorpions” from that American dad episode

  2. Lone_Ghost_Jinn

    Crap.  I thought this was cool and then I remembered your novel Ancestor and I’m freaking out a bit  6 months from now there will be four foot long supersoldier ants kicking down our doors and taking a cup of sugar.

    I hate it when Science Fiction became Science Fact…Mufasa…shiver…say it again, say it again…Mufasa…shiver

    omg. The size of those heads! Creeptastic.
    I dig that it just took a little awakening of ancient genes to make that happen. Makes me wonder what dormant monstrosity genes we humans have lurking *shudder*


    I would place a few of those little buggers on the sandwich and start eating. Just think of all that protein.

    How would you like to be at picnic and find one of these things crawling towards your sandwich…
