A Magic Crystal? (Marvin Redpost 8)

Marvin Redpost has a girlfriend—not a real girlfriend, just a girl who is a friend. And Casey Happleton is no ordinary girl. She lives in an old firehouse and she has a magic crystal! She wants to share the crystal with Marvin. Could the crystal really be magic? Or is Casey putting her own spell on Marvin?
 
Hilarious and relatable, Marvin Redpost is perfect for kids who love to bond with quirky characters like Junie B. Jones and George Brown, Class Clown.
