The series is called Obsidian Heart, and the first volume is titled THE WOLVES OF LONDON, due for delivery in spring 2013.

Alex Locke is a rough diamond, an ex-con turned psychology lecturer, who one day receives an offer that he cannot refuse. What follows drags him down into a nightmare more terrifying than anything he could ever have imagined, a nightmare in which he is pursued not only across the country, but ultimately across time by the fabled Wolves of London, a group of ruthless assassins with unbelievable powers at their fingertips. Blending crime, horror, steampunk and dark urban fantasy, Obsidian Heart is a huge, phantasmagorical jigsaw puzzle of a story told in three very distinct parts, each with its own unique atmosphere. Full of twists and turns, it is a Weaveworld for the twenty-first century – brash, audacious and packed with surreal and outrageous imagery.

Cath Trechman said: “We’re delighted to be publishing Mark Morris’s brand-new series Obsidian Heart. It’s a dark supernatural time-travel thriller which readers will find impossible to resist.”
