The rats of Ghedassir are turning nasty, secretly preparing an attack by their vengeful master, the True Lord. Can young ratter Ternan stop them?
Alone in the world but for his close friend Linzi, Ternan ekes a living from catching rats on the wharves of Ghedassir. He's the best rat-catcher in town, but his extraordinary skills attract attention from unexpected quarters.
A sinister brotherhood, calling themselves the Faithful of the True Lord, protect the rats, which seem to be carrying out a secret mission.
The rulers of the City of Ghedassir, the Intercessors with Those Departed, have a guilty secret. They are snatching street urchins to do their dirty work, betraying the trust of the people they serve.
And a hidden Tribe, practitioners of forbidden magic, keep watch over Ternan and Linzi for they know that these youngsters, unbeknown to them, are destined to lead their City in a war against an ancient and vengeful evil - the War of Hidden Places.
