An electrifying novel about the creeping reality of political terror, and the violent pleasures found in Brooklyn's queer heartlands. Part noir, part erotic thriller, X is a vivid, moody and darkly funny portrait of those living on the margins of an increasingly hostile society. Broke and discontented, amateur sadist Lee spends their days working for a big corporation and their nights searching the warehouses and dungeons of Brooklyn looking for the mysterious, seductive, and bloodthirsty X.

In a sly purging of migrants, refugees, sex workers and queers - any citizens they claim to be undesirable - the US government has started exporting people, and Lee has heard X might be among those about to disappear. As their obsession with X grows, Lee becomes further enmeshed in the crimes and dramas of the city's queer community, following ex-lovers, playmates, clients, best friends, and accidental accomplices through damp and shining bars and parties looking for any lead that might bring them closer to X, before she vanishes for good.
