Rory and Derek do everything together, and they are looking forward to a terrific summer. At least that's what they think . . . until they're ordered to be friends with a guest in the neighborhood. Not only does Bolivia have a weird name, but she's a girl — definitely not someone either boy wants to get to know. Of course, Bolivia does have that great pet parrot. And she does have good ideas for boy-style fun, like making ice cream into ammunition for a summer snowball fight. But while Derek is willing to admit that he likes Bolivia, Rory won't even be nice to her. The boys have a fight that could ruin their friendship forever, and then Derek goes away to camp. Left alone with Bolivia, Rory has to admit that playing with her is more fun than playing alone, and that maybe his resistance to her was just reluctance to admit he'd been wrong. Could it be that this whole time when he and Derek were doing things "their" way, that they were really just doing them Rory's way? When Derek comes home, Rory finds out what it really means to be a friend. Readers will cheer for the success of the three-way friendship as they get to know each of the realistically drawn characters. Johanna Hurwitz, author of such popular novels as Class Clown, Class President, and Teacher's Pet, makes this story come alive with all the drama and humor of childhood.
