One word sums up this series. Fantastic. The book is based in Perdido Beach, America. It's about a town which has been incased in a mysterious, impenetrable bubble, every one above 15 years old has simply vanished, some kids develop supernatural powers and there's an ominous evil who strives to undermine the kids.
The main reason this series is so captivating is the fact that it address issues such as racism, sexuality etc in such an intricate manner. The book is predominantly based on 'survival of the fittest' the strong survive whilst the weak do not. It's similar to Lord Of The Flies.
This series is a HUGE recommend!
