I recently read The Spirit Thief and while I probably will never be someone to read series back-to-back, I will at least try not to put too much time in between different books, especially since I liked the first book a lot.
The Spirit Rebellion picks up right after the previous events (so I was glad not much time had passed since I read it), but it went off to a rather slow start as Eli and Co are on some sort of side quest cleaning up after the first book, and Miranda has her own repercussions from those events. Eventually the story does pick up and provides a nice new quest.
While it was a very enjoyable read and I like the interaction with the spirits and the magic in general, I do have to admit that the bad guys are not very fleshed out besides being evil, very evil. On the plus side, no romance but powerful friendships which is so refreshing!
Onto the next book!
