Heartsong (Green Creek #3) by TJ Klune

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 has bounced 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, Robbie will learn that packs and homes can disappear in an instant.
