Shawn Davis grew up in the small town of Holliston, Massachusetts. He earned his Bachelor of Science Degree in Criminal Justice from Salem State University, and he works as a police officer in a small New England town. He also worked as a police lieutenant at a New England College for eleven years. Shawn's background in law enforcement lends authenticity to his crime thrillers.

Shawn is also the co-author of the real-life WW II adventure, Never Surrender, with his Great Uncle and protagonist of the story, Earl Anderson. Never Surrender is the true story of Earl's incredible experiences fighting the Japanese in the Philippines and then surviving for three and a half years as a POW in Yokohama, Japan.

Shawn also co-authored the Sci-Fi Thriller, Revolution, with his friend from high school, Robert Moore. American Insurrection is a high-tech, adrenaline-fueled, action-adventure story about a violent future rebellion in the United States.
Shawn also authored the edgy horror thriller, Blood Kiss, which details the reign of terror of a coven of beautiful female vampires at a small New England college.

In addition, Shawn authored the gritty crime thriller, American Criminal, which describes a former cop's struggle to survive in prison after being set up by his corrupt partners on a drug force tactical team.

In the novel, Bounty Hunter, an indomitable anti-hero drives an armored battle-car through a post-apocalyptic wasteland, fighting a deadly array of post-nuke enemies.

In the horror novel, The Soulless, written with co-author Mark Mackey, an army of zombies and genetically engineered monsters is let loose by a female mad scientist working for the government.

Finally, in Diary of a Serial Killer II: Ice Man, Shawn follows up his first popular horror novel in the Serial Killer Series by introducing a deadlier psychopath based on the notorious Ice Man, Richard Kuklinski. The victim-turned-heroine in Book I, Tracey Randall, returns as an indomitable detective tracking the killer in Book II.
