Caitlin Dare is an FBI agent attached to a Swat team. She gets booted off the team for going off script and taking risks. Her own partner betrays her. She gets reassigned to a new task force to police the railways. A murderer has taken to killing women on the train. She is paired with a railway policeman who has a similar experience with his job. They do not work well together and are in competition. Finally they start to work together to solve the mystery of who is the killer. Very dramatic chase at the end.

Another great story. Sadly I know serial killers murder a lot of people but wish there weren't as many deaths in our crime stories. Can give them more ideas and don't like giving them that attention. Couldn't stop reading until the end. Fran Fran

It keeps you wondering about if they would get the killer before there’s more victims.

This isn’t the normal genre I read, but I wanted to check it out in the free section! A definite good read, I loved the suspense and story build!

It was a fast-paced read, couldn’t put it down!! I don’t purchase books, but can’t wait for the next time I see a Molly Black book to get free.

This book has it’s good parts but it’s too predictable and too convenient. And there’s not enough action for me.

An excellent read. Good pace. Good dialog. No gratuitous sex and language - just a good mystery unraveled. I recommend.

I really enjoy reading books by Molly Black. Come get me,was a good easy read, but a little predictable. Still enjoyed it.

An action packed thriller.

Excellent start on this series. Fast read and intense at times. Can’t wait for the second book.
