'Heaven must be missing an angel ... The angel Bethany and her mortal love, Xavier, have already pushed the boundaries of Heaven with their relationship. In this conclusion to the Halo trilogy, the two take their love to the next, forbidden, step: they marry. At a time when they believe nothing will come between them again, they are faced with their most daunting challenge yet - The Sevens, a military order of angels designed to maintain balance in the universe. These soldiers won't stop until their job is done - capture the wayward angel and send her home. Beth discovers there is only one way back to Earth, but the cost is higher than she ever imagined. If she can survive, she can prove to Heaven and Earth that there is nothing stronger than the power of love.'
