Just a few hours left for Hollow World Giveaway

We are coming down to the wire on the last giveaway for Hollow World, which will end in about 14 hours. Winners will not only receive signed print copies, but they will also get the ebooks in a variety of formats.

Early reviews have been coming in from those who doing the pre-order promotion, Net Galley Readers, and those in Amazon's Vine Program.  Here's what a sampling.

“This book made me laugh. It also made me cry. And in the end, it made me think. I highly recommend Hollow World for anyone looking for a book that brushes on and plays out some political and social issues we face today.”  —N. E. White, SFFWorld.com

“Hollow World establish Sullivan as a force to be reckoned with in any genre he chooses to ply his talent to.” —Matt Gilliard, 52 Book Reviews

"This is social science fiction that H.G. Wells or Isaac Asimov could have written, with the cultural touchstones of today. A modernized classic, Hollow World is the perfect novel for both new and nostalgic science fiction readers." —Justin Landon, Stafffer’s Book Reviews

“Michael J. Sullivan has made a name for himself with his excellent series of fantasy novels and Hollow World proves he can deftly tackle science fiction just as skillfully. The ideas are big and the future plausible, this is one of those rare gems you'll be thinking about long after you put it down.” — Bryce Lee, Only the Best Science Fiction & Fantasy

“Hollow World was easily one of my top reads of 2013...I rate this book highly based on pure enjoyment factor; Hollow World is so many things, but without a doubt, the best part about it is also its most obvious duality: that is it at once a light and entertaining read, but also heavy on important issues and philosophy.” — Stephenie Sheung, The Bibliosanctum

I hope you'll have a chance to enter before time runs out, and congratulations to the winners!
