Not for me I'm afraid. It's an ambitious story, but there's just too much going on here. And, fair enough, novellas are a tricky length. But this is less than 30,000 words, if I understand it correctly, and it crams in demons, psychics, Greek gods, zombies, a brosnie (some kind of mythological reptile?), Druidism, human sacrifice, and dodgy goings on at the Russian embassy. It's too much, and as a result justice is done to none of it. There's no room to really explore anything, and the main character, who comes across all this strangeness on the first day of his new job, is given no real space to react to any of it.
