The Same Blood. The Lamb and the Lion: Wolves Among Us, #2

Blood will tell. Life is better for Jem Berger. He's got a job that he's good at. He's got a boyfriend he loves. He's talking more with his mom, even though he's not sure if he should call her mom. And there's been no sign of the murderous pack of psychopaths Jem and Tean ran into a couple of months before. Sure, it's not a job he loves. And things with Tean have been.weird lately-therapy, mood swings, a growing sense of distance.
And when Jem's mom calls, it's not like they have anything to say to each other. But overall, things are definitely better. Until, that is, a snowstorm traps Jem and Tean at a resort in the Wasatch Mountains, and they find themselves caught up in another murder-one in which Jem's mom is the prime suspect. Worse, Jem and Tean discover that the resort isn't as isolated as they thought. And someone is hunting them.
