This third adventure has Opal trying to find what her new role in life will be now that she no longer has her glass magic. She goes on a search for some of the blood that was removed from her in the previous book and along the way she encounters a variety of villains and makes a number of new friends. Her romance with Kade gets pushed aside as she reconnects with Devlin. She is also recruited by Valek and trained by him to help her meet her goals. I enjoyed Opal's journey and was happy with the resolution at the end of the book.A number of characters from earlier books reappeared in this book. We got a chance to see more of Nic and Eve and Janco and Ari. We also saw Mari and Leif again as Opal helps her mother get ready for their big wedding. We also see Opal's character as she helps a number of people while she is on her quest. Opal is a compulsive fixer. She can't pass by anyone in trouble.I liked her relationship with her horse Quartz. They were partners. They communicated and Opal finally realizes that she is gathering her own herd of people who are impartant to her. I recommend the series - Storm Glass, Sea Glass, and Spy Glass -- to lovers of fantasy who appreciate strong female characters and a well-developed system of magic.
