Rockin' Rockets (The Adventures of Allie and Amy, Bk. 2)

Allie and Amy are best, best, best friends. Rockin' Rockets, their favorite group, is in town! The concert is sold out, and no one has tickets - no one except Gracie Barnes, who has an extra one.

Gracie just moved to the neighborhood, and both Allie and Amy think she is funny and cool and nice. But with two friends and just one ticket, whatever Gracie chooses can only spell trouble.
