Dayna's homecoming coincides with Cedarwood's Blood Moon Festival, an event the town hasn't recognized since 1969 after four girls were murdered at six month-intervals after the last celebration. The murders have all but been forgotten until a fatal accident on the night of the first moon, another six months later, and a third, six months after that.
Sanctuary Road comes full circle on the night of the fourth and last Blood Moon celebration when secrets from the past collide with sins of the present, and Dayna finds the love she thought she'd lost is still within her reach.
