Landslide

Jimmy Carter will take control of the White House. Americans are meeting Laverne & Shirley at their apartment in Milwaukee. Hotel California diverges from the reign of Kool & the Gang. And the FBI is still reeling from the repercussions of Watergate, the tragedy at Wounded Knee, Operation Family Secrets, and the strategic terrors of the anti-cult movement.
That's what Special Agent Harry Styles has been told is the basis of his mission to an abandoned farmhouse in rural.
With his hair grown out long and his shirt untucked, he's going undercover to do reconnaissance on suspected cult leader Louis Tomlinson, who has led a group of people out into the middle of nowhere, leaving no record of the life he'd had before. All Harry knows is what the agency gave him: Tomlinson's name, and instructions to figure out what he's doing with the eleven people he brought with him.
In the year that Harry spends undercover and under Louis Tomlinson's wing, he learns more than he ever expected.
