Lockdown

The main storyline probably isn't all that original. Children in a prison trying to escape (at least a couple of them). And some mutilated guards and dogs thrown in for good measure. But the story is fast paced and the book is short so you'll have it finished before you know it. Basically it's just the first installment in the series so I'm curious how things are going to work out. Wouldn't be surprised if this is turned into a movie.
