My thoughts: I received this book from the publisher for review, and I was so pleased when they contacted me because I've been dying to find out what would happen next to Opal. This is the third and final book in the Glass trilogy featuring Opal Cowan the glass magician. At the end of the second book (Sea Glass, read my review here) Opal lost her powers, and in Spy Glass she is on a quest to find her blood hoping she can regain some magic.
I was pleased to see that some of my favourite characters from the previous books were also in this one. I was especially pleased to see Ari and Janco again because I really love them.
I mentioned in my review of Sea Glass that there was a confusing appearance of the Bloodrose clan that I hoped would be cleared up in the third book. They did reappear in this book and the mystery surrounding them seems to have been resolved.
One last point to make is that if you've been following the series you'll know that Opal has been torn between Kade and Devlen. By the end of this book she has finally made the choice. I don't want to give anything away, but I think after reading the book I can understand her choice.
I really enjoyed this book, and I think it was a good end to the series. But there were some new characters introduced in this book that I really hope Maria is going to write some more books about!
