Delta is eager to begin her life as a loyal Guardian. But she's more special than she thought, placed in training as a Power-Holder, with a destiny kept from her until she's old enough to handle it. Adding to the stress of her training is the terrifying memory of a vision, a secret kept by her closest friend, her sister's disappearance right before Delta's announced as future leader, and the yearning to be like every other wolf. But Delta is not like every other wolf.
