Dying by the Hour - Kory M. Shrum

Dying by the Hour is the second novel in the Jesse Sullivan series. This book isn't free, but the series is good enough I'm willing to pay.

It's been about a year since Jesse escaped the clutches of the Unified Church. Jesse, Ally, and the crew are still up against the minions of Caldwell. People are disappearing. Caldwell isn't just kidnapping people with NRD, he's kidnapping the people who death replacement agents have replaced. It turns out there is a special category of NRDs. Caldwell is one. So is Jesse. The action is fast and bloody. Very highly recommended.
