When Daisy moves into the palatial Weston mansion, she expects a fresh start for her and her mother, James Weston's soon-to-be bride. What she doesn't expect is to be trapped under the same roof as her long-time high school crush: her future stepbrother, Zach Weston. But living together quickly shatters her illusions. Daisy soon realizes that Zach isn't the sweet boy she admired from afar—he's arrogant, manipulative, and seemingly determined to make her life a living hell.
