While I've read plenty of books with Jeff VanderMeer's name on the cover, it's generally been preceded by "edited by" rather than "written by". As such, Finch is the first Ambergris novel I've read. It's a very atmospheric novel, with a great deal of style. The city of Ambergris seems quite alive, just as China Miéville's Bas-Lag is a rotting corpse of a city. It's a gritty detective noir story, and the fungal atmosphere really works. While there is obviously backstory with some of VanderMeer's other Ambergris novels, each takes place at a different point in the city's history, which means that the previous stories are alluded to, rather than requiring knowledge. It works rather well for those coming to his fiction for the first time.
VanderMeer seems at home with the mystery genre, and the plotting makes sense once the story is done. The further I got into this book, the harder it was to set down, as if fungal spores had grafted themselves from the book into my hands. The plot tension of the novel ramped up, and VanderMeer's narrative kept pace.
VanderMeer plays with the liminal. The occupying forces are fungal creatures, not truly plant, nor animal. John Finch is a detective, but working for the occupying forces. Blending things even further are the Partials: human-spore hybrids, accepting greater power in the occupation, but equally feared by everyone. While there's a strong sense of independence and rebelliousness in the human detectives like Finch, the Partials strongly evoke the feel of collaborators in the war-time occupations in Earth history.
Finch is a very stylistic novel, with a near perfect mix of plot and characterization. It raises issues of colonization and living in an occupied state, something which resonates strongly in many areas of the world today. A very enjoyable read.
