Gehenna. The end of everything for the vampires. It had been building for years in the World of Darkness game books and novels. And here we have it.
The novel mostly focuses on Beckett, the Gangrel archeologist/historian/Noddist scholar and that was a sensible choice. He is on a quest for answers and we get to tag along. Many other notable vampires come in to contact with him along the way.
The story does have the scope and feel of an end of the world situation. So that worked for me. Beckett and his search was reasonable and decently depicted. If you're wanting a decent story centered around Gehenna I'd give this a shot. It's not the best Vampire novel I've read but certainly not the worst.
