Another fine book by Christopher Moore. This is number three of a series; the first two were Bloodsucking Fiends (read back in 2011) and You Suck (read in 2016). As you almost certainly guessed from the titles (because I can tell you are a good guesser, reader), vampirism is involved.
I don't much care for vampire books, but it's Christopher Moore, and he does a great job of infusing the genre with humor, profanity, likeable and interesting heroes, nasty villains, and unexpected sweetness. As a consumer note: if you decide to tackle the series, I don't recommend taking a span of seven years to read them. Important plot details fade on that timescale.
Many surviving characters from the previous books are here: Tommy, the aspiring writer from the Midwest, now turned undead, and trapped inside a bronze statue. But he's trapped therein with the lovely Jody, also a vampire. Unfortunately, their help might be needed because there was another cliffhanger in the previous book: Chet, the huge shaved cat, was also vampirized, and he's busy vampirizing other cats, and they've taken to terrorizing the Streets of San Francisco. Initially removing street people, mostly the homeless and hookers, but on their way to eliminating everyone.
Also present is the delightful, R-rated, teenage goth, Allison Green. She calls herself Abby Normal, and she's thrown herself into the vampire thing with a passion. She desperately wants to be one. And (small spoiler) she gets her wish. But (another small spoiler) this turns out to be a very bad idea.
A lot of fun.
