Still suffering from the same issues as the earlier books in the trilogy.
Seriously, this whole trilogy could have been dealt with in one book. If this had been developed like one of her earlier books, it could have contained this story & more, as well as had more satisfying characters. I like Mags, but his friends were unbearable. Even The Bartimaeus Trilogy (whose characters I mostly disliked, across the board) had more character development, & a better denouement then this story. I do still read a lot of children's and YA fantasy, and this trilogy, with a few small edits, could have very easily qualified as a children's series. Sorry, Ms. Lackey.
