Malarkoi: Cities of the Weft, Book 2

Nathan Treeves is dead, murdered by the Master of Mordew, his remains used to create the powerful occult weapon known as the Tinderbox. His companions are scattered, making for Malarkoi, the city of the Mistress, the Master's enemy. They are hoping to find welcome there, or at least safety. They find neither - and instead become embroiled in a life and death struggle against assassins, demi-gods, and the cunning plans of the Mistress. Only Sirius, Nathan's faithful magical dog, has not forgotten the boy. Bent on revenge, he returns to the shattered remains of Mordew - only to find the city morphed into an impossible mountain, swarming with monsters. The stage is set for battle, sacrifice, magic and treachery in the stunning sequel to Mordew. Welcome to Malarkoi.
