Oddly enough, I've read two books this year about teenaged girls trapped on deadly, deserted islands. The first, Bad Girls, was written by a man, and it showed. The girls were stereotypically competitive with each other, there's a scary and disgusting sexual assault, and at one point one of them has her period and cries over having had to stick toilet paper "up there." Without going into details...no. Just no. Worst of all, it was melodramatic and overwritten.
This book is silly and at times frenetic, but it's also a story that I would love my little sister or (hypothetical) daughter to read. Sometimes you just need some girl power.
Why isn't this a movie yet?
