Lash by L.G. Castillo (Broken Angel 1)

Decades after being banished from Heaven for saving a life he shouldn’t have, Lash is given a chance to redeem himself. His mission: protect Naomi Duran, a young woman who has lost her faith. The assignment proves to be anything but simple when his superiors, the Archangels, withhold key information about Naomi and refuse to restore Lash’s powers. When an unexpected source reveals centuries-old secrets, his trust is shaken to the core, and he begins to doubt those whom he had once considered to be his greatest allies.

Determined to avoid anything that would risk his chances of returning to Heaven, Lash struggles with the greatest obstacle of all—his growing feelings for Naomi. But when her life is threatened by an unknown source, Lash questions the wisdom of the Archangels and his ability to keep her safe.

Soon, Lash will have to choose where to place his faith—in the home he has fought so hard to regain or in the forbidden love he can’t bear to lose.
