The distinctive feature of the Chaos Walking world is telepathy, with the interesting twist that women don’t broadcast. Crucial to the second book is the further twist that some men don’t broadcast either. One such is the evil and manipulative President Prentiss.
That word manipulative is particularly important, because it brings me to the main way in which Ask didn’t work as well for me as did Knife. The main characters Todd and Viola are manipulated by Prentiss and by his arch-enemy, Mistress Coyle. That would be fine, had the author’s manipulation of these and other characters not seemed intrusive.
That said, I found Ask engrossing, and Ness does move the pieces into place for a cliffhanger even more dramatic than the one on which Knife ended. So I’m looking forward to Monsters of Men, the third book, which is due out next year.
