My full review is here on my personal website. I'll post a few excerpts here, though:

3.5 out of 5.0 stars

The very worst thing about this book is either the predictability or the unoriginality. There are some unexpected moments, but overall it’s fairly predictable. Also, the author borrows obviously from other stories. Not that it is unusual to borrow, but it does seem unusually obvious.

The very best thing about this book is the world that Clare has created. The way the different species interact and their histories.
