3.5-4 stars. I think I liked the second one better, but I did enjoy this one. It was predictable, but still good, the right combination of sexual tension and hotness. Love the other characters, and having read the 2nd one first, I got to see a few things from a different point of view.
Not quite sure about the whole "You give up heroin and I'll give up Ryder" thing, but I am willing to overlook that conversation.
Will be continuing with this series.
