Welcome to the Grandest Game, an annual competition run by billionaire Avery Grambs and the four infamous Hawthorne brothers, whose family fortune she inherited. Designed to give anyone a shot at fame and fortune, this year’s game requires one of seven golden tickets to enter. With millions on the line, those seven players will do whatever it takes to win. Some of the players are in it for the money. Some for power. Some for reasons all their own. Every single one of them has secrets.

Avery Grambs has a plan for a better future: Survive high school, win a scholarship, and get out.

To receive her inheritance, Avery must move into sprawling, secret passage-filled Hawthorne House, where every room bears the old man's touch - and his love of puzzles, riddles, and codes.
