The Glass Trilogy concludes with Spy Glass and Opal Carew has to make some serious decisions in this book. After reading it back in June I had to take some time away to think about it because so much happens in this book. Opal flounders around in the beginning trying to understand her new standing in life as a person immune to magic, much like Valek I believe and she has trouble adjusting.
After some time recovering she ask her friends about the time during captivity and she realizes that something does seem right, something important of hers is missing. Then she goes on a quest, breaks into jail, breaks out of jail, finds something of hers, loses something of hers, gets addicted to something, and makes a hard choice about her life and the lives of others.

Loose ends having to do with the odd community by the sea from the second book are tied up when she is forced to return there. During her time there her own magic is forced upon her and she becomes addicted enough to begin to understand Devlin's side of his own struggle with his addiction. While she fights her growing attraction to him she also fight keep herself and many others alive.
This book is very hard to summarize without giving too much away but it is packed with emotional roller coasters and life changing events for Opal, thus it is not to be missed. This review is based on the Galley edition.
