Anna Windsor - Captive Spirit

Saving humanity from the supernatural has been challenging lately—even for a well-trained earth Sybil like Bela Argos, who must harness the magic of a fractious group of warrior sisters and battle a new wave of paranormal attacks. Another challenge is Duncan Sharp, the hunky NYPD detective who might turn into a demon overnight and devour Bela in her sleep. Still, the darkness taking over Duncan’s body can’t stop the molten heat unleashed by the intense attraction between them.

Duncan has two major problems: First, he has the soul of a suspected serial killer hitching a ride on his vibe. Worse (yes, worse) he’s got a demonic fever raging inside that promises a world of hurt for everybody, especially Bela. Now he’s all about getting even with the demons that put this freak curse in his blood—satanic forces that dare to unleash their savage lust on Duncan’s soul, his city, and the woman he loves.

Comment: This is a new book on the world of Sybils. The author has another trilogy already based on this world, which ended in a bittersweet flavour.
This new book is the first of a second trilogy, and right now there's a new enemy.
The heroines are also characters from the previous books, and now we see them once again together to defeat some demons.

Bela Argos is the "leader" of a new team and she wants them to work out, while still mourning the ones who died.
She's afraid they won't be able to work together but she's making an effort. In comes Duncan Sharp, a police detective, someone who shows up at the wrong moment, but in the end that's what allows him to live long and in a useful way.

I think this book lacks a certain something to make it memorable. I liked it but I wasn't dazzled by it. The same had already happened with the previous trilogy. The writing is logical and makes sense. The characters are serious and with depth. But I think they're too serious, there's almost nothing in the humour department, the reader doesn't see them having fun...I understand the tone of the books isn't a funny one, but once in a while it would be nice to watch them in a more carefree environment.
Besides that, I think this world has everything to be a winner.
I'll read the following books when I can.
