Return of the Runebound Professor (Book 5)

Inquisitors are hot on Lee’s tail. Though she managed to defeat the latest one, victory came at the cost of Azel’s life… and the inquisitors are far from their greatest threat. Wizen continues his advance toward Arbitage. His goals are still unknown, but he’s powerful enough that even Renewal and Decras acknowledge his strength — and the threat he poses Noah’s group. Ancient plans are coming to fruition, and they're centered around the last person anybody would have suspected.
