At long last, the incomparable Roberts leaps into the paranormal genre in a big way! Roberts wastes no time kicking off a trilogy that immediately immerses readers in a complex mythology that will require much dedication and sacrifice from its protagonists. Like her earlier trilogies, intriguing pairs of disparate couples must band together for a common goal. Book one does an excellent job of setting up the seemingly impossible quest and introducing the "Circle of Six." Once you start, you won't want to stop this thrill ride.
