The Hot and Cold Summer

Rory and Derek are best friends forever....At least that's what they think -- until they meet Bolivia. She's visiting next door all summer and everyone wants the three of them to be buddies. But since she's a girl, Rory and Derek decide to ignore her completely. Except it's not so easy to ignore someone who has her own pet parrot and who likes to make snowballs -- out of ice-cream!Derek starts thinking Bolivia's the funniest, craziest kid he's ever met, but Rory still says three's a crowd. Is there room in their friendship for Bolivia, or is she about to break up a perfect team?
