Conclusion to the Bone Mask Cycle! Notch finally holds the answers he sought, along with an unsuspecting Sacrifice... but drawing all the pieces together will prove a greater challenge – especially when it becomes clear that the Fura Leones does not approve of such desperate measures. In Renovar, Flir must find a way to salvage the bones of the frozen Sea God but Chelona has other plans for the mighty corpse, and trapped within her now is Seto, whose frustration can only build as he watches over but cannot warn his friends. Equally troubling is the floating city of Ilesinya, which now hovers dangerously near Anaskar, seemingly poised to strike. Lord Danillo is drawing together his allies in a final gambit to defeat Chelona and her unstable creation, Zasemu, but none know her true plan... and when it becomes clear, all lands will face a threat like no other.
