Mermaids! Sisterhood! A little bit of darkness, I can get into a book like that.Only, oh. :( They're mean mermaids and the whole book is a bunch of catty passive aggressive arguments with sprinkles of undying love that makes no sense at all. Even our main heroine, who is above all this petty arguing and competition (only she's not really), can be rather cruel and thoughtless. It doesn't feel like a deliberate move on the author's part, it comes across as weak story telling and enforces the good old fashioned stereotype that girls cannot get along with other girls. This book had some interesting concepts, only it was ruined by unlikeable characters. Blech.
