#1 Over the Net (Jake Maddox Girl Sports Stories) by Jake Maddox
Description of the book:
Allie loves everything about volleyball except hitting. She doesn’t think she’s good at it, and every time she messes up, her belief in her own abilities dwindles. Finally, she asks for help. Her idol, Nikki, agrees to coach her once a week. If Allie can learn to spike as well as she blocks, she could become one of the team’s strongest players.
