The Wolves of London: The Obsidian Heart - Mark Morris

Alex Locke is a reformed ex-con, he's working on staying out of that world until he receives an offer he can't refuse and he agrees to steal an artefact, and everything goes horribly wrong, he's caught up with complicated and messy supernatural goings on and he has to try to wind his way through, stay alive, rescue his daughter and possibly save the world.

Entertaining but lacked something for me.
