Fatal Exchange by Lisa Harris is mostly an edge-of-your-seat action packed thriller. It starts off with action pretty fast, though it doesn't lay down a good base of who is who--I got pretty confused right off the bat. This is the second in a series and I didn't read the first, I suppose it would be a good idea for someone else to do so.
The storyline was very real and scary (gunman in a school) and it made me nervous to read it.
Towards the end it felt like it was wrapped up too fast, like the action just abruptly ended and the book was finished.
I enjoyed it and it kept my attention. I do wish that I'd been aware that it was part of a series and that I'd read the first one before this one.
