The Guardian

After Hunter prays to the angel Gabriel to protect him, he is shocked when a motorcycle rider appears to answer his prayers

Hunter has spent his life going from foster home to foster home—he’s never had a real family looking after him. When his foster father dies, he is left at the mercy of his abusive foster mother, Stephanie, who resents Hunter for coming into their home and ruining her perfect life. Between living with Stephanie’s cruelty and dealing with the school bully, Hunter feels like he has no one to turn to—except for the angel Gabriel, who visited Hunter when he was a kid and promised he’d always watch over him. Although he hasn’t spoken to Gabriel in a long time, Hunter is desperate to avoid getting beaten again, so he prays for help—and Gabriel answers.
 
Every time Hunter asks Gabriel for something, he receives it. Is he really being protected by a guardian angel? Hunter can’t believe he could ever be so lucky, but if an angel isn’t protecting him, who is?
