Simplicity

In 1977, a group called the Spiritual Association of Peers escapes to the woods of the Catskills, taking over an abandoned summer camp. They name their new home Simplicity. In 2081, scholar Lucius Pasternak, a fastidiously organized trans man, tries to keep his head down living in the New York City Administrative and Security Territory. Then he's offered a job by the mayor, billionaire real estate developer Dennis Van Wervel, to complete an anthropological survey of the people of Simplicity for the history museum Van Wervel is financing.
Lucius, though wary, is nevertheless drawn in by the community, intrigued by its strange rituals and in particular by the charming acolyte Amity Crown-Shy. But Van Wervel's project is more sinister than it seemed, and members of the community begin to disappear, leaving behind grisly signs of struggle. Lucius and Amity set out to hunt for whatever's responsible in the dangerous Exurb Zones, a wild wood full of libertarian doomsday preppers, wealthy isolationists, and worse.
There they'll finally discover the true threat to Simplicity and its way of life - and what they're willing to do to stop it.
