Captive Soul moved the back story of the Sybils and how the 3 remaining elements evolved after the Water Sybils were killed a lot. This book concentrated more on the plot and less on the romance thank the previous 5, although there was plenty of heat when the romance was center stage.
John Cole is living in a different body, cohabitating, as it were, with a demon. He was previously coinhabiting Duncan's (from Captive Spirit) body. Camille managed to wrest him out of Duncan and into his current host, Strada. His soul also mingled briefly with Camille's, so to say they have a history is a bit of an understatement. John spemds months in the Strada body watching Camille, trying to learn to control the demon so he doesn't hurt her. He enlists the help of another set of good demons, who help him control his darker impulses.
Camille feels like a failure for letting Strada get away. She adds this to the long list of perceived failures on her part, such as being unable to generate Fire, her element. Without giving too much away, she and the rest of her quad find out they have different abilities than other Sybils. We are given vignettes into Camille's past, how she always feels like an outsider, like she isn't good enough, and how destroyed she was when her first Triad was killed. She is a very sympathetic character, but never falls into the wimpy category.
John is the type of hero who is always going to do the right thing, regardless of his own personal cost. He has put his whole life into fighting the demons, only to find himself inhabiting the body of one of his sworn enemies. He puts Camille on a high pedestal. He declares his intention to his best friend, Duncan, to marry her almost from their first "live" interaction. He is goal oriented, and so completely in love with Camille. He's afraid that one day, the demon inside him will get the upper hand, though.
We don't have a whole lot of scenes with just Camille and John, but the ones we do have count. I love how Anna Windsor writes love scenes. It's more than just sex. It's touching, caressing, holding...it's the characters enjoying each other on a whole different level than a lot of writers bother with. This can be in an actual sex scene, or when they are in a group and Camille leans into John to show support, or he puts his hand on the small of her back...it's the attention to the romantic detail that gets me, and Ms. Windsor is really, really good at the details.
This book is action packed and never really lets go of the reader. I could have done without the level of POV of the villians, though. Honestly, I skimmed some of it, then realized there was information about the Sybils hidden in their viewpoints, so I had to go back and reread. The pace is quick and the resolution was satisfying. The end was perfect, and I can't wait to start Captive Heart!
