Spoiler:

The only surviving son of a small-time career criminal, Cal Rakowski is a young man intent on living an uneventful life. A natural problem-solver, he earns good money as an off-the-books auto mechanic, working side-by-side with his friend Lebell in a Bridgehampton garage owned by a wealthy businessman named Eric Carver. But Cal’s idyllic existence is turned upside down when dark forces target the pregnant friend he is sheltering. And when his two closest friends are revealed to be more than what they claim, Cal’s innate survival skills are put to the test. Forced to do battle with a sudden onslaught of enemies that include a brutal thug, an abusive and powerful ex-husband, and a well-funded female assassin seeking her own personal redemption, Cal’s only hope is the darkness that has always dwelled within him—a darkness he must now unleash if he is to save the one life he has sworn to protect. Set over the course of three days—Mischief Night, Halloween, and the Day of the Dead—The Violet Hour is a powerful and unrelenting thriller in the tradition of such classics as The Postman Always Rings Twice and Marathon Man.
