A narrative in letters. Promise Goodday sent to a mental institution for killing her child, writes letters to her childhood friend Lakeisha Ann. For almost twenty years, Promise has endured the atrocities of Rust Hills--drugs, questionable "therapies," and sexual abuse from a person she named "Big Fingers" are just some of the horrible experiences. The letters, searing, sad, and sometimes comical chronicle her life at Rust Hills. Is there escape and redemption in the end? Is Astroworld a real or make-believe place?
