Eve of Destruction: Marked, Book 2
Brand: Audible
Class is in, but Evangeline Hollis is struggling to get through the requisite training to be a full-fledged Mark. When her class goes on a field trip to an abandoned military base, passing the course isn’t just a matter of pride...it’s a matter of life and death. There’s a demon hidden among them, killing off Eve’s classmates one by one.

As the body count mounts, a ragtag team of cable TV ghost hunters unwittingly stumbles into the carnage. Now keeping the Mark system secret competes with the need to keep the "paranormal researchers" alive. With Cain on assignment and Abel on an investigation, Eve must fly solo on her hunt to stop a killer before he strikes again.
