Something sinister brews deep in rural Wyoming; a movement; a liberation; an uprising. Meanwhile, chasing loose ends in Nassau, King and Slater witness an act so shocking they can hardly comprehend it. They realize they have no choice but to investigate, abandoning the Bahamas for the Thunder Basin National Grassland in Wyoming. Their pursuit leads them to a shadowy cult occupying a commune in the isolated heart of the prairie. Mother Libertas, led by their mysterious and seductive messiah Maeve Riordan, is like nothing King and Slater have ever seen before. Its followers are fueled by a mind-bending drug known only as Bodhi. Alongside Alexis and Violetta, they go down the rabbit hole in order to destroy the cult, but they end up fighting not just for their survival, but their sanity.
