You are royally NOT invited ...Juliet Henry is turning seven. For her birthday, she's planning a pink princess party-for girls only! They'll all wear pink clothes, make pink crowns, and eat pink food. Who wants boys at a princess party, anyway? But Billy and the other boys in Juliet's class are mad. They love birthday parties ...and hate being left out. If this pink princess isn't careful, her loyal subjects could ruin her birthday bash!
