The Scandalous Sisterhood of Prickwillow Place

While the plot is not hard to predict, the characters are what make this entertaining. The girls range from tween to early teen, so while they're very young, they're intelligent and capable, free of the usual angst and dramatics you might have expected otherwise. The plot is kept light-hearted and overall amusing, even adding a little romance now and again.
An adventure full of character and charm, the story is as much about the mystery itself as it is about the friendship between the girls.
