In Time I Dream About You — Gene Gant

Gavin Goode was a star athlete and a good student until one catastrophic decision destroyed his future. As a member of the savage street gang the Cold Bloods, Gavin ran afoul of the leader, Apache, a bigot determined to punish Gavin for his sexuality. After being framed for a crime he didn't commit, Gavin faces a prison sentence -- and the promise of relentless rape and torment. With his spirit almost broken, Gavin learns his beloved father has suffered a near-fatal assault. But a friend appears when Gavin needs him most. Cato has been masquerading as a prison guard when in reality he is a time traveler -- one with the ability to wipe the slate clean for Gavin… and his father. 

But changing the past will threaten the future for many innocent people. Gavin finds himself trapped between saving his father and himself or accepting the steep price of preserving the time stream.
