My least favourite of the three, but still an enjoyable read. Its real strength is in the ending, I think, which isn't really happy by any stretch of the imagination but is still all too believable. I'm always left slightly saddened, however, by the wrong boy dying. The narrator, Will, can be so sulky and rash (albeit in a normal adolescent way) that one can't help but think the three boys around him are much better suited for life in the new world. Funnily, my strongest memory of reading this series as a child was the feeling of utter betrayal regarding Henry. (Clearly I hadn't read a lot of characters who ended up as he did then...)
