This is book 4 in the Cassie Raven series and I recommend reading them in order to understand Cassie's character and her relationship with Flyte. It is a great series. I love Cassie's character and Flyte has grown on me throughout the series. I need more of the two interacting though. They are so different and work so well together. I enjoyed the addition of DI Bacon and I look forward to seeing more from him. He defintely wasn't what I was expecting. The hint of supernatural with Cassie hearing from the dead is done well and left open for the reader to decide whether it's a gift or just subconcious attention to detail. The Investigation is full of twists and turns and made harder by the fact they didn't start investigating straight away. I had no idea who had killed Sophia or why and the ending was heartbreaking.
