Rating: 3.5/5 
 ***Minor spoilers, spoilers for books 1-5*** 
 The Ruby Circle begins with Adrian and Sydney's married life in court, which isn't really the happiness they hoped it would be. Adrian is unsafe at court, since people dislike him for bringing a human. Sydney is unable to leave the suite they're in because there are too many threats to her, and she's less able to protect herself than Adrian. Things aren't really looking up until Mrs. Terwilliger, Sydney's mentor, shows up at court with what appears to be a clue about Jill's whereabouts, and so plans are made to get Sydney out of court without anybody knowing. 
 I'm quite sad that I'm finally finished with one of my favourite series, one that I've been reading since the beginning. I'm quite happy with how things ended up, but it'll be hard to let this one go. At the end of the author's note she does say that she'll probably be coming back to this universe, so at least I have that to look forward too. 
 In all honesty, I was a bit disappointed with this book. It wasn't that it was bad, it was just that for some reason I didn't enjoy it as much as I hoped to. I feel like it's partially because I haven't read any other Richelle Mead books since I started writing reviews on Goodreads, so I'm a lot more conscious of little things in a book that bug me. I feel like this is one of my least favourite books in the series, but it was still quite good. 
 I found the beginning a bit slow, but things picked up soon enough. I don't particularly like when authors separate the main couple, even if it isn't for the entire book. I just find it a bit frustrating that there was all this build up for Adrian and Sydney being together and they had to be separated AGAIN. I found Silver Shadows pretty frustrating to read for that reason. 
 What I loved most about this book was that we got to see Dimitri, Rose, and some other characters we grew to love in the Vampire Academy series. I'm hoping that in the future Mead gives us more Dimitri and Rose, because (view spoiler)[ with learning they could potentially have a child, I'm excited to know what they're going to do with that information (hide spoiler)]. 
 Overall, this book was enjoyable enough, but not my favourite in the series. I found it a satisfying end to the Bloodlines series and it didn't leave me with any questions. If you've already read up to book 5 and enjoyed them, definitely finish off the series, since it's great to know where the characters end up. Since I'm done this, I may revisit Vampire Academy, since it's been maybe 3-4 years since reading the series.
