Rhyden Fabhcun has faced many challenges and enemies in his life. In the third installment of this epic adventure, he faces what could well be his greatest yet — the vengeful and powerful spirit of a long-dead queen, Mongoljin Burilgitu. Summoned by the Oirats bitter enemies, the Khahl, Mongoljin has an appetite for souls and is bent on preventing Temuchin Arightei from claiming the dragons lair. She will stop at nothing, and will destroy anyone who stands with the boy who would be king — including Rhyden.
