Vulnerable

Probably closer to 3.5. Like the other novels from this author, they're very engaging. Like, extremely. This one is right in the middle between straight up mystery and romantic suspense.

The ONLY thing, though, is that the other thing I noticed about this author is that she seems to consistently take the creepy factor a bit too far. We very quickly go from creepy to gross and a new level of disturbing. That definitely and unfortunately takes away from the enjoyment of the story.
