Jupiter Rising

When Jack's P. E. coach pairs him up with Jay Perkins for the cross-country team, neither of them is happy about it. Jack is grieving the loss of Joseph, his foster brother, and adjusting to his role as big brother to Jupiter, Joseph's orphaned daughter. Dealing with Jay Perkins-who'd once ganged up with his buddies to jump Joseph in the locker room-is the last thing he wants to do. But then Jack realizes that Jay is grieving too-the loss of his cousin Maddie, Jupiter's mom.
As Jack's relationships with both Jay and Jupiter grow and his running improves, he starts to feel more like himself than he has since Joseph died. He's finding his stride .
