It's called Bear Country, an untamed alternate reality where humans never evolved, but saber-tooth tigers and suspiciously intelligent little green monkeys did. Random chunks of Bear Country are temporarily swapped-exchanged-with Earth, bringing a risk-averse, bubble-wrapped society unimagined threats, from giant bears to the hazards of unknown bacteria. They also bring opportunity for anyone brave enough-or crazy enough-to settle there. Computer guru Sharon Mack prepares to evacuate when she finds out her town is about to be Exchanged . But when her crazed ex-husband kidnaps their autistic daughter, dragging her into Bear Country, Sharon has no choice but to go after them, find her daughter, and escape before the Exchange reverses, cutting her off from her own reality forever. Flash floods and giant bears aren't the most dangerous thing in this wild frontier. Bands of escaped convicts, with nothing left to lose, roam freely in a land with no laws but survival of the strongest. Then there's enigmatic Leo West and the secretive Sister West cult, determined to claim Bear Country for their own. And there are those willing to kill to hide the true secrets of the Exchange. Exchange is the first book in the Exchange universe. The second is Devouring Wind, available now.
