This is the second book in the Chaos Walking Trilogy, and I must say, it's my least favorite. It has some cool features, such as the young main character discovering he has powers he can exert with just thoughts--which Ness actually fits into the story world rather than adding them simply because they're cool.
The frustration comes in with the two main characters' apparent inability to stand up for themselves. Time after time, they do things they disagree with or even find repugnant, with their only opposition being some denial that the acts will change them.
I still think it needs to be read in spite of the flaws, though, as the trilogy wouldn't be the same without it.
