It's Christmas in Sedona, Arizona, and Santa's not the only one coming to town.... Twenty-five years ago, Grace Rinehart's father -- an alien-human hybrid -- sacrificed his life to save Sedona from an invading army of reptilian aliens who called themselves "the masters." Their base was destroyed, but something...someone...survived. Now Grace's alien DNA has called her to the remains of the alien base, where she finds what was left behind, the prototype for version 2.0 of an alien/human hybrid super-soldier. Grace doesn't expect to lose her heart to the one man she knows she shouldn't love. And when the secrets he's been hiding come to light, she has to face the truth of what the Reptilians have been planning all along...even if it means destroying the only true happiness she's ever known."
