In Song of the Ovulum, a fiery battle between dragons and the military helped Matt and Lauren set their father, Billy Bannister, free from a demonic captor. The demon, however, escaped and kidnapped their mother, Bonnie. During the battle, a portal vortex flung Matt into oblivion, and no one knew where he went.    Now, in From the Mouth of Elijah, Lauren and Billy set out on a journey to find Bonnie, hoping Lauren’s gifted hearing can track down Bonnie’s never-ending song. At the same time, Walter and Ashley search for clues to cure a mysterious disease that threatens to kill the original anthrozils, including Jared, who was once the great Clefspeare.    Both journeys are fraught with peril as Lauren and Matt are thrust into Second Eden, where a volcano, Mount Elijah, has erupted and devastated the land, killing many of the residents.
