Slave - Sherri Hayes
There are books that are quietly unputdownable. They don't have a lot of action going on, no shocking sudden twists and turns, no explosions or fights or chases thrown at you left and right, and yet they have a quiet pull that forces you to read on. This is one of them.

I almost finished this in one go, I was so enthralled and engaged in the story, the characters, and the burning question of how this would develop, what would happen next (in terms of quiet character development), and how this was going to end.

And because it has a mean, mean cliffhanger, I am now off to read the next one, ASAP.
