Three woman. Three keys. Each has 28 days to find her way through a dangerous quest. Nora Roberts brings us a unique series with a twist-each novel is written in real time, and the novels will be published in consecutive months.

A mysterious invitation brings three very different young women to Warrior's Peak, a castle-like estate outside of Pleasant Valley, Pennsylvania, where their enigmatic hosts offer the opportunity to participate in an unusual quest. Each of the women will have 28 days to find one of the keys to a mystical box, which holds the trapped souls of three Celtic demigoddesses.
