This book starts out great. Hooks you with the first 30 pages and then doesn't let up for another 200. The strength of the first part earns this book two stars, but it's all downhill from there. Some SPOILERY content follows, although I keep it vague.Most of the conflicts in the latter two-thirds of the book depend on characters not stating the obvious topics of conversation to one another. Cronin continually uses "Deus Ex Machina" devices to allow his characters to escape. Literally, God intervenes through the characters' "faith" so that otherwise impossible events needed to perpetuate their lives/the plot can occur. Add to this an ending revelation of a character's survival whom we thought had died, that, if you think about for about 30 seconds, means the entire castastrophe could have been halted/greatly lessened in its early stages if this person had bothered to, say, use a phone or cell phone or radio. If you want a satisfying humans vs. vampires book, I'd heartily recommend E.E. Knight's vampire earth books instead.
