In the Shadows of Night

When Isaac signed up to be a werewolf, he didn't know the deal included sharing a roof with a creepy undead thirty-something guy who might be trying to seduce him. And Peter can be very persuasive and surprisingly considerate when he wants something. As Isaac tries to figure out his treacherous feelings while battling nightmares about his father, Derek is looking for the Alphas and trying to protect his pack. And if that means spending most nights with Stiles doing research, well, it's really none of Isaac's business.
