Annie Barrows and illustrated by Sophie Blackall, Ivy + Bean features two spunky seven-year-old girls, each one pressured by her mother to become friends.
Bean, a sassy, puddle-stomping spitfire, takes an instant dislike to Ivy when she moves into the house across the street. Ivy seems boring and nice, not friend material at all. The pair unite when they take on Bean's eleven-year-old sister Nancy. Ivy, although quiet and seemingly demur, has hidden qualities--she can belch on demand and she's a witch, or at least a witch in training. The two girls join forces to create a spell that will have Nancy dancing nonstop. By the end of the day the pair have pulled off the spell with hilarious results and in the process have become fast friends. Since that first book, six more in the series have been published.
