Not as good as the previous books, but it has it's upsides because after all that mushy who shall I choose? and all, in this book they weren't really main characters, they just were mentioned a few times and the main point was that she didn't want to see them anymore, now she's still confused but she'll try less than running to the other side of the world and out of town.
Another good thing is that we got to read about Edward, which was nice after all the times that he popped out, and mentioned even without popping into the story.
Third nice thing is that we had assassins as the main characters, which is a change from having vamps and wereanimals hogging all the good stuff (not that I protest to that, if it's the right ones like Damian and Jason). Plus the Olaf character really appeals to some dark part in the readers.
A down side is that the story was long, all the finding out who's the monster was really long and I got bored here and there.
