In Hawkins Hollow, Maryland, three boys performed a blood-brother ritual at the Pagan Stone on their tenth birthday and accidentally unleashed something ancient and malevolent. Every seven years, The Seven descends on the town, driving residents to violence and madness. Now, twenty years later, Cal Hawkins and his childhood friends Fox and Gage face the worst outbreak yet—and three women with uncanny gifts have been drawn inexplicably to the town, each partnered with one of the men by forces none of them fully understand.

Cal Hawkins, Fox O'Dell, and Gage Turner are blood brothers whose different temperaments—Cal's steady leadership, Fox's easy optimism, Gage's restless cynicism—make them effective as a unit. Across the trilogy, each man's partnership with his matched woman forces him to open what the demon's shadow has kept closed.

The Sign of Seven trilogy follows the six protagonists—three friends and the three women fate binds to them—as they research the demon's origin, piece together the history of Hawkins Hollow, and work to find the weapon that can end The Seven permanently. Each book focuses on one couple while advancing the collective investigation and supernatural threat. The tone blends paranormal suspense with romance, culminating in a high-stakes ritual confrontation at the Pagan Stone.
