Soon, he enters a high-stakes game of manipulation where trust is in short supply.
The Rat Specialist: Some informants live behind new names; others are left exposed. Corey's job is to keep them clean, breathing and, when they fail, build the case that sends them back to prison. But the people he supervises are experts at betrayal, and some would rather kill him than trust him. And in Corey's line of work, one misstep can put him directly in the path of the bullet meant for someone else.
Suicide Watch: Leaving his previous job behind, Corey Sullivan lands in the quiet mountain town of Barlowe, Oregon, hoping for an easier life. A campus security job seems like the perfect choice, but soon Corey finds himself surrounded by thrill-hungry officers who see him as dead weight. When two deaths on campus are ruled suicides, Sullivan's instincts kick in. And once he starts pulling at the threads, he won't stop until he finds out the truth.
