The Zurian Child — Jessica E. Subject

Lindsay Beckett longed to be reunited with her first love, Quinn Montgomery, until she learns the secret that sent him fleeing from her in the first place. He's an alien, a Hemera, and she's half-Hemera herself. As if that wasn't enough to ruin her dreams of a perfect life, when their child is born, they discover she fulfills a prophesy told twenty light years away and many years ago. Lindsay wants to ignore it, until her husband is murdered and suddenly believing becomes a matter of survival. Lindsay and her young daughter are forced to rely on another Hemera, her husband's partner and best friend, Bryce Beuermann as more and more of the Hemera are slaughtered. Bryce will do anything to help his best friend's widow--including suppressing his own deep feelings for her. But he must prove they can trust him, even pretending he doesn't want her with all his heart.
