Mage’s Marines by Saria Bryant

Max Savino has spent his whole life refusing to conform to the expectations of his father, the head of the Denver mafia—until his defiance crosses the line and his father decides he’d rather have a dead son than a disobedient one. Instead of waking up dead, Max wakes up with a power he only dreamed he could possess.
When his father sells him to a pack of shifters, Max finds himself in a world he doesn’t understand, claimed by three wolves and fighting for control over his new magical flames. He’ll have to learn to trust these dangerous men and the devotion they’re promising him, because now that Max’s father knows he’s a mage, he wants him back—and he doesn’t care who he has to kill to get what he wants. It’s time for Max to stop running if he has any hope of protecting his future… and the pack that’s somehow become the family he’s always wanted.

Mage’s Marines is an action-filled urban fantasy featuring an overpowered fire mage, three super-sexy Marine shifters, and a fight for survival.
