The beloved fantasy romance sensation by New York Times bestselling author TJ Klune, about love, loyalty, betrayal, and joy. The Bennett family has a secret: They're not just a family, they're a pack. Heartsong is Robbie Fontaine's story.

All Robbie Fontaine ever wanted was a place to belong. After the death of his mother, he bounces around from pack to pack, forming temporary bonds to keep from turning feral. It's enough-until he receives a summons from the wolf stronghold in Caswell, Maine. Life as the trusted second to Michelle Hughes-the Alpha of all-and the cherished friend of a gentle old witch teaches Robbie what it means to be pack, to have a home. But when a mission from Michelle sends Robbie into the field, he finds himself questioning where he belongs and everything he's been told.

Whispers of traitorous wolves and wild magic abound-but who are the traitors and who the betrayed? More than anything, Robbie hungers for answers, because one of those alleged traitors is Kelly Bennett-the wolf who may be his mate.

The truth has a way of coming out. And when it does, everything will shatter.
