Childhood friends. Decades of hidden feelings. A bond never meant to break- until it shatters.
Blurb: Ryan Kelly has known Zach DeShawn was his mate since they were kids. Just when Ryan is ready to finally tell Zach how he feels, he inherits his grandmother's magic. If Ryan can't learn to control his magic, how can he protect his friends from the danger his grandmother predicted with her dying breath?
