Waterfire. The Ridnight Mysteries, #3

The thrilling conclusion to The Ridnight Mysteries!After returning to the East, Zev Asterling attempts to put away his Master-Solver days and rebuild his life. Political tensions have run high since the events at Ridnight Castle, and a summit between the Frontier and the East is a sliver of light that many cling to. But when a politician's daughter is kidnapped, Zev is called upon to do what he does best.
With the help of Axon, Pilot, and Bellemont, they must find the daughter in order to avert an all-out war. Along the way, his companions will have to resolve their feelings about the gods, their nations, and each other if they want to make it out alive. Zev will have to set aside long-held grudges and family issues to deal with a threat the likes of which no one has ever encountered before, as his investigation takes him deep into the bowels of the city, pits him against a bizarre cult, and forces him to battle rogue witches who have the power to destroy the entire East.
Waterfire is the final chapter in The Ridnight Mysteries, a stunning high fantasy mystery trilogy from Stuart Jaffe, author of The Max Porter Paraormal Mysteries.
