Wolfsong by TJ Klune

Ox Matheson was twelve when his father taught him a lesson: Ox wasn't worth anything and people would never understand him. Then he left. Ox was sixteen when the energetic Bennett family moved in next door, harbouring a secret that would change him forever.

For the family are shapeshifters, who can transform into wolves at will. Drawn to their magic, loyalty and enduring friendships, Ox feels a gulf between this extraordinary new world and the quiet life he's known. He also finds an ally in Joe, the youngest Bennett boy.

Joe is charming and handsome, but haunted by scars he cannot heal. Ox was twenty-three when murder came to town, and tore a hole in his heart. Violence flared, tragedy split the pack and Joe left town, leaving Ox behind.

Three years later, the boy is back. Except now he's a man - and Ox can no longer ignore the song that howls between them. Wolfsong is the first book in the Green Creek series by bestselling author TJ Klune.
