La canción del corazón

Robbie Fontaine has wandered from pack to pack his entire life, but what he's always wanted is a place to call home. He thinks he found it in Caswell, where he lives quietly. But when a mission takes him away from the pack, he discovers that nothing is as it seems. Robbie then begins to question everything. There are whispers of treachery among the wolves, but who is telling the truth? Who is lying? And why does he have strange dreams every night where the moon implores him to come home?
