Miranda Day, known as Mama Day, is the elderly matriarch of Willow
Springs, a small sea island off the southeast coast of the United
States. Mama Day finds herself pitted in mortal combat with dark forces
that threaten the body and soul of her beloved great-niece, Cocoa, who
has gone "mainside" and married an urban northerner. Mama Day will use
her ancient knowledge of herbal medicine and her judicious but dangerous
use of magical powers in this bitter struggle.
