In the third book of the Bloodsong Saga, faithfully set in the mystical world of Scandinavian mythology, Bloodsong faces the greatest enemy she has ever known—her own son, Lokith, the demon of Helheim. Once destroyed by his mother, now Lokith is back with a vengeance, allied with the Death Goddess Hel and supported by a vast army of her fearsome Death Riders. Armed with only her sharpened sword and the dark-beast powers that are her heritage, Bloodsong must face her son's blind fury and battle the foul forces of Hel as she searches for an ancient long-departed army that may be her—and the Earth's—only hope.
