I thought we would be done with Sacred Valley after the events of the last book, but it turns out that those were just set up for this one. The gang is back in Sacred Valley, this time delving into the Labyrinth beneath, a dangerous place full of ancient powers and relics. The lure of the Soulsmith knowledge buried within is enough to convince Lindon and Eithan to take the risk, but the fact that Reigan Shen is already in there makes it a priority for everyone. Shen is there hoping to become immortal by turning himself into a Dreadgod and he must be stopped before it happens. At the same time, the Abidan are waging war in the heavens also trying to save Cradle, and the time finally comes for both series of events to finally come together in a big reveal.
Reaper - the truth about Eithan is revealed
