Absolutely superb. I found the first book (The Enemy) a little slow going, trying to be a little too large in scale. This second in the series is a bit more focussed and significantly better for it.
There’s no escaping the gore and bad language. This is a young adults’ book with the emphasis on “adult”. Don’t expect all the characters to survive, either. As Higson made clear in the first book, nobody is safe! This makes the book all the better as it’s very difficult to work out who’ll make it to the end.
The final couple of chapters tie up with the first novel (the events in this one take place – up until that point – prior to The Enemy) nicely without spoiling that book too much if you’ve not read it.
A very good read and highly recommended. And as a bonus, you don’t have to have read The Enemy to enjoy it. I’m going to have to get hold of The Fear now!
