The Shadow's Bite

"One bite from a nightmare was all it took to turn Kael's life into a graveyard. After waking up to find his family and neighborhood destroyed by his own hands, Kael has been a monster on the run. But he isn't a normal werewolf-he is a Shadow-Born, possessed by an oily, ethereal power that even Alphas fear.
When he saves two fellow wolves, Liam and Maya, Kael finally finds a pack. But his past is catching up. Under the mentorship of a powerful Alpha named Silas, Kael must learn to control the darkness before the original Shadow Wolf-the one that bit him-returns to finish what it started. The training is over. The hunt has begun."
