The Ruby Circle is the sixth and final installment in Richelle Mead’s Bloodlines series. It picks up about a month after where Silver Shadows ended. Sydney and Adrian are living in the Moroi court, the only place where they can be assured protection from the Alchemists, who are still intent on punishing Sydney for her marriage to Adrian. Meanwhile, everyone is searching for Jill, who disappeared without a trace at the end of Silver Shadows.
Like the previous two books, The Ruby Circle is told from both Adrian and Sydney’s perspective, and Mead continues to handle the dual perspective well, staying true to the inner voices of the characters that we have come to know over the past five books. We also see how Adrian’s continued hallucinations of Aunt Tatiana speaking in his head are affecting him, and how much he continues to struggle with his use of Spirit.
