Immortality, the #1 best science fiction book of 2008 by W Thomas Payne
No. 1 - "Immortality" by Kevin Bohacz capitalizes on the theme of impending environmental collapse and the rapid extinction of species that we read about daily in the national news. Following in the wake of the Hugo-award winning novel "Darwin's Radio" (Greg Bear), Bohacz keeps the reader riveted with a tale of how the rules of evolution when being crushed by environmental factors could create new species that are "hidden" amongst us - including fellow members of the human race.

Kirkus: If you thought Immortality was powerful, just wait until you read the sequel. Blending fierce action, twisted conspiracies and bold "transhumanist" visions, Bohacz once again drives readers through a whirlwind in which even the characters aren't sure if their thoughts are their own or if they were installed by the god-machine... Bohacz constantly raises the stakes, and the crisp dialogue and well-drawn characters keep the story barreling forward.

Publisher's Weekly STARRED review: Bohacz provides mind-bending portrayals of factions vying for power and reflections on the essence and fragility of humanity. But philosophical concerns never obtrude on the fast-paced plot, as authorities investigate communes of hybrids, and Freedman and Mayfair must choose between absorption into a collective mind or fidelity to their remaining humanity. The question of who can be trusted impels the reader to keep turning the pages of this highly satisfying and dynamic techno-thriller.

S.J. Higbee: Bohacz manages to provide a gripping plot with plenty of twists and turns that kept up the tension right to the very end. Bohacz has aimed very high with this techie yarn about why we are here and what might happen next – and even if techno-thrillers aren't normally your favorite genre, give this book a go. I'm betting that you'll still be thinking about it when some of your favorite authors have faded into the furniture.
