Obsidian and Onyx. So on with my review of Opal.
After the deaths in the last book, Katy's friendship with Dee is almost nonexistent. Dee does kind of blame Katy for what happened, not directly, but because Katy hadn't kept her in the loop about what was going on with Blake, the human who had been healed like Katy, and now had the connection to his own alien. But at the end of the last book, they told Blake to never come back. Only, he shows up again. And they're on the lookout for the guy who made Daemon heal him last time, Katy's mom's boyfriend.
There is a little good news, Daemon and Dee's brother Dawson is home again. But all he can think of is rescuing his human girlfriend. And so when Blake comes back saying that he knows where they are and has a friend who can help them get in to save them, Daemon and Katy realize they have to try to work with him. We meet some new characters, other humans who have been through what Katy and Blake have been through. We also learn of another stone, opals, that have an affect on them. Opals are helpful though. (Yay! My birthstone!) They will have to go through a lot to get into this place and save Dawson's girlfriend and Blake's friend. Daemon and Katy's relationship will just get stronger though, even through all the tough times. There will be another loss of a friend, and once again there will be betrayal. They will take care of one threat, while adding another.
And the ending, that ending! I'm so glad I have the next book on my shelf already. I just need to fit it into my reading schedule soon! Again. If you haven't read this series, you need to. Let me share with you my reactions as I read through this book with my Goodreads status updates.
