In this perfectly pitched novel-in-letters, autistic eleven-year-old Vivy Cohen won't let anything stop her from playing baseball--not when she has a major-league star as her pen pal.

Vivy Cohen is determined. She's had enough of playing catch in the park. She's ready to pitch for a real baseball team.

But Vivy's mom is worried about Vivy being the only girl on the team, and the only autistic kid. She wants Vivy to forget about pitching, but Vivy won't give up. When her social skills teacher makes her write a letter to someone, Vivy knows exactly who to choose: her hero, Major League pitcher VJ Capello. Then two amazing things happen: A coach sees Vivy's amazing knuckleball and invites her to join his team. And VJ starts writing back!

Now Vivy is a full-fledged pitcher, with a catcher as a new best friend and a steady stream of advice from VJ. But when a big accident puts her back on the bench, Vivy has to fight to stay on the team.
