Well, most of the book was pretty badass, as was to be expected from the others. The relationship between the two young assassins grows more complicated, amusing, embarrassing, and interesting throughout the book. However, the climax of the story was a bit unsatisfying, due to the fact that everybody suddenly went from relying on skill to relying on magic that they'd never previously explored--basically, they got brand new powers. And the way they defeat the hordes of enemies closing in on them from all sides was ridiculous, I hate to say it. These are complex, resourceful characters. I was hoping the resolution would hinge on their previously demonstrated abilities, not random magic that had no basis in the other books.
