This is not the type of work that I read; however, some Amazon friends reviewed this and I became intrigued. After having read this excellent thriller, I'd like to share my thoughts.
First, the cast of characters is quirky, including immortals, such as demons, angels, imps, vampires, and a succubus. And a strange creature that I had never heard about before, foreshadowed, of all things, by Scripture. The central character is a charismatic succubus, Georgina Kincaid. A succubus leads a life that is intriguing--shape-shifting, libidinous life style (although it can cost her lovers time off their life span and worse), immortality. Georgina works in a bookstore in Seattle, populated with mortals and immortals. Her snappy one-liners, putdowns, and so on make her an interesting and even likeable character--despite her effects on her lovers.
The bawdiness and humor take a dark turn when two immortals come up dead and two others attacked and hurt. Much of the rest of the volume focuses on the efforts of the immortals, led by a demon and an angel, to determine who the villain is and how to stop the attrition of immortals.
And, as a complicating part of the plot line, Georgina is interested in two very different men--Roman and Seth. On the face of it, she is torn in an impossible situation. Developing a physical relationship with them would wound them badly (at the very least); her attraction to them without being able to go any further is a torture in itself.
At any rate, the novel moves toward a tense confrontation and sets the stage for sequels. A reference to Peleus and Thetis (pages 342-343) suggests some future twists and turns. And I would, against all odds, be interested in looking at those sequels, one of which, as I understand it, is already out. This is well written and a real hoot; the pace moves ahead with great momentum.
