Camberforge War by Mike Connor

Jack Landon’s world turns upside down when a former enemy shows up in his hometown of Cabbington. Fleeing into the woods seems a great idea until he finds out he’s not the target. Instead, it’s his best friend Max. Terrible choices loom when Jack attempts a rescue and makes a fatal error. Obtaining a second chance in heaven, he has to complete a series of challenges if he wishes to keep the newly created timeline in place. Jack must work in a military academy ground, while also winning over a man-hating witch, taming a wild beast, facing pains of the past, using a sword with no blade, and trying not to die again.
