Hoop Rat [PDF ebook] 

Trey Mc Tiernan, the Spartans‘ team captain, becomes fast friends with Griffin Henshaw, the newest member of their squad. The problem is, Griff used to play for the Spartans‘ biggest rivals, the Goliaths, and the rest of the Spartans‘ think he’s a rat. So, Trey’s teammates set a trap for Griff to see where his loyalties lie — and they ask Trey to be the bait! Trey doesn’t know what to do. If his teammates are right, then betraying his friendship with Griff will save their season. But if they’re wrong, then Trey will end up being the rat . . .
