A Cinderella story with deadly stakes and thrilling twists， perfect for fans of One of Us is Lying and Knives Out。

Avery Grambs has a plan for a better future: survive high school， win a scholarship， and get out。 But her fortunes change in an instant when billionaire Tobias Hawthorne dies and leaves Avery virtually his entire fortune。 The catch？ Avery has no idea why--or even who Tobias Hawthorne is。 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。

Unfortunately for Avery， Hawthorne House is also occupied by the family that Tobias Hawthorne just dispossessed。 This includes the four Hawthorne grandsons: dangerous， magnetic， brilliant boys who grew up with every expectation that one day， they would inherit billions。 Heir apparent Grayson Hawthorne is convinced that Avery must be a con-woman， and he's determined to take her down。 His brother， Jameson， views her as their grandfather's last hurrah: a twisted riddle， a puzzle to be solved。 Caught in a world of wealth and privilege， with danger around every turn， Avery will have to play the game herself just to survive。
