Rich man, poor man, freeman, or slave. When red fever comes calling, no one is safe.

Captain Ezra Burton brings a ship load of problems to Bristelle and seeks Godwyn Bethwood's help to soothe the way. If he thought he had problems when he docked, it soon gets worse. Godwyn is dead and now he must deal with his sister and the indomitable Evie Chester.

Burton's problems seep out on to the streets of the city. Sickness and infection spread unchecked whilst the medics and city men don't even think there is a problem. Evie and Hesta know better. They cannot ignore the danger and must act to overcome the perils that threaten to overwhelm the city.

When the city is overwhelmed and all feels lost, more extreme magical measures are needed to save them. It takes a summoner, a killer, a healer and a cleanser to attempt what no one has ever tried before. Yet there is a price to pay for this immense outflow of power. Which one of them will pay the price?
