It's a little sad to see the quartet broken up this series, and I'm going to miss seeing them all together this whole quartet. But I can see why they have been, and the fact that this series is going to work on them developing independently, instead of continuing to grow more codependent on one another. 

This book follows Sandry and her new student. It is a little more mature than the previous series, and was unexpectedly dark/gruesome in some spots, but in a way that works and that I think probably works well, too, for upper-Middle Grade fiction. 

Anyway, overall I enjoyed reading this quite a bit.
