Sandwiching this one right between the first two in terms of enjoyment. 

As in both previous books, the twists are telegraphed from the beginning (Ada really enjoys telling us everything she's going to do), but again, this does not detract from the story at all. If you're looking for a puzzlebox, this is not the series for you. 

If, however, you're looking for fun, science-fictional, criminal shenanigans, you could do a lot worse than this series. 

Other reviews had me prepared to be disappointed by a lack of resolution, but I'm satisfied with where it ends. If we get more, I will probably read them. If we don't, I'll still recommend the trilogy (with some caveats for romance readers).
