Gav Thorpe’s Ghost Warrior is the first book in the Rise of the Ynnari series detailing the exploits of Yvraine and her Ynnari, whose goal is to bring forth the aeldari god of the dead, Ynnead. When the Iyandeni are confronted with the return of the long-lost craftworld Zaisusthra, spiritseer Iyanna Arienal’s path intersects with Yvraine’s. Iyanden needs allies to survive, while the Ynnari see an opportunity to find and claim the last of the once-lost Croneswords, which they need to bring about the awakening of Ynnead. The question is, what does Zaisuthra want, and why has it returned now?
