"Kleier's undeniably gripping second spiritual thriller is bound to provoke just as many arguments as his controversial first novel, THE LAST DAY. THE KNOWLEDGE OF GOOD & EVIL is the first of a trilogy, and Kleier's many fans will only hope they won't have to wait long for the next installment."
“One of the most intriguing tales of the decade.”
--Clive Cussler, NEW YORK TIMES bestselling author of THE WRECKER
“A tough, savory, formidable thriller layered with plenty of angst and adventure. Glenn Kleier is a pro who delivers his promising premise with a flawless execution.”
--Steve Berry, NEW YORK TIMES bestselling author of THE PARIS VENDETTA
“A fantastical puzzle of mystery upon mystery set against the broad tapestry of a fierce, diabolical running battle that actually culminates in heaven and hell. I defy anybody to put this one down!”
--David Hagberg, NEW YORK TIMES bestselling author of THE EXPEDITER
"This thought-provoking, exhilarating thriller asks many questions about religious dogma as Kleier questions contradictions between free will and forbidden fruits. The story line is fast-paced."
--Harriet Klausner, AMAZON #1 reviewer.
