Long Night Moon. Seasons of the Moon, #3

Something is killing innocent people around Rylie Gresham's town. The police think it's a wild animal, but she has other suspicions. There are new kids at school, and they have a lot in common with her: gold eyes, super strength, and a habit of turning furry. It seems Rylie's not the only werewolf around anymore. It's up to Rylie and her werewolf-hunting boyfriend, Seth, to stop the killings. But saving lives doesn't come naturally to a monster, and territory battles could risk the life of her sickly aunt-not to mention her own.
Rylie has no choice but to stand her ground, protect her home, and stop the murders before anyone else gets hurt.
