Gr 6–10—War looms large in this exciting third installment of the series. Following a dangerous encounter with the diabolical Dr. Phoenix, the Smiths find themselves hunted by both the Ordo Draconis and Order of Brenden. Worse, Phoenix is using the Dragon's Tooth to build a powerful army that he plans to unleash on the Order. Just when things seem the bleakest, Cyrus and Antigone uncover a ray of hope hidden within a set of cryptic instructions willed to them by the late Billy Bones. To prevail in this impending battle, they must release the ancient powers imprisoned within Ashtown's forgotten tombs, and they do so at terrible risk. Meanwhile, Cyrus continues to be haunted by the prophecy warning of The Desolation, one whose coming would make "even dragons" tremble with fear.
