Deathseed (The Weirkey Chronicles #8)

Betrayed. Murdered. Reborn. One last chance, to make it right. Theo's adventure ended with his mentor's hands around his neck. The betrayal cost him his friends, allies and everything he had built... but not his life. Though broken and powerless, Theo has one last chance to enter the Nine Worlds, wielding the knowledge and expertise of his first life. This time, he needs more than just power, he needs to unravel the deception that killed him once... and is coming for him again.

Theo and his allies have ascended to Authority, but new power means new challenges. They're capable of changing the Nine Worlds, but those worlds haven't waited for them to gain power. Something foul is growing back in Tatian, threatening everything Nauda holds dear. Friends and enemies from their entire journey will come together in a great struggle where every decision has consequences, and the tiniest of details might save or ruin everything...
