"Money is the reason we exist, everybody knows it, it's a fact". When Kayla Diana Grambs, sister to Avery Kylie Grambs inherits 40 billion something dollars from an old Texas billionaire she's shocked. Her life turned from living with her sister in a car and dealing with their other sister's abusive boyfriend, to living the American dream. All she must do to claim this inheritance is stay in the Hawthorne Mansion for a year. The catch? She doesn't know who this billionaire is, nor does she know why she was left the money or why he's left a game for her and her sister to play. She does however know that 40 billion dollars and a bunch of estates isn't the only thing she was left by this billionaire. She also has to live with his grandsons, one is a nomad cowboy, one a human rube Goldberg machine, one a ticking time bomb, and one over worked accountant who might be the devil himself: Grayson Davenport Hawthorne.

Lila Skylar Hawthorne was never meant to be part of the game. Too quiet, too soft, too busy hosting imaginary tea parties and playing music while the rest of the Hawthorne family tore itself apart over riddles, secrets, and a fortune built on manipulation. While her brothers chase clues and outwit one another, Lila grieves a grandfather she loved and struggles to hold her place in a family that seems to forget her more and more each day.
