They Thirst

Vampires take LA in this epic battle of good v evil. It's down to a grumpy policeman, a bullied schoolkid, a comedian on the verge of mega stardom, a dying priest, a gutter journalist, a drug dealer, a spiritualist, man who has lived in the sewers for 20 years and a little bit of the Pacific Ocean, to save humanity from the terrors of vampiredom.
This book is great fun with few dull moments and the ending is really good, something Roland Emmerich would be proud of.
