Upriver

When two Navy SEALs are accused of murdering a fellow commando in Iraq, NCIS Special Agent Linus Schag is sent into a war zone to bring them back alive.

But before Schag can take them into custody, an IED explosion gives the fugitives a chance to escape. Stealing a Navy patrol boat, the SEALs flee upriver into territory controlled by ISIS—and Schag is ordered to bring them home.

With the help of an Army investigator and a vengeful Iraqi interpreter, Schag launches a deadly pursuit through one of the most dangerous regions on earth. Ambushed at every turn and hunted by enemies on all sides, he must uncover why two elite warriors would risk everything to run.

Because the truth hidden upriver is more dangerous than murder—and it could send them all straight into the heart of an ISIS-made hell.

Editorial Reviews:

"What sets this solid military thriller apart is the realistic depiction of the effect multiple deployments have on both the professional military and reservists who are called up to assist and train the shaky Iraqi government. While delivering on the action, Hill also shows us the terrible toll on civilians as well. Uncompromising and highly recommended!" (James Benn, author of the Billy Boyle WWII mysteries)

"A must read ... Overall this was hard to put down and difficult to fault. It's given me a desire to go back and read books 1 and 2." (Reedsy Discovery)

"Upriver offers a finely developed and ambitious plot that supplies plenty of tension and action. Hill's straightforward, clear writing style is a solid fit for the subject matter and pace of the novel.

Hill's knowledge of Navy Seal operations is apparent throughout the novel, as he develops characters with both nuance, depth, and realistic flaws." (BookLife Prize)
