In A Jam (Roller Girls) Kitap Açıklaması: Annie and Tyler are going out! OK, he can be a bit controlling sometimes, but Annie's never had a boyfriend before so she assumes that's what they're like. Her roller derby team, the Liberty Belles, are in top position in the league - but are they getting over-confident? Annie misses a few practice sessions so she can spend time with Tyler. As punishment, she gets left on the bench at a big bout. The whole team needs to refocus - especially Annie.
