I liked the characters. I could see why Jessica was the way she was. Same with Noah. But FCOL, I called the villain the first time they appeared on the page. I was disappointed that Noah was so tunnel visioned when it came to his conclusion of who the villain was.
So while I liked him as a person, I thought him a tad incompetent.
I did like the writing as well, and the secondary characters. I'll read another from this author to see if her heroes get any better at their jobs.
