Winnie spent years in law school and has been living on a law clerk's meager salary - the only job she could find - while her older stepbrother, Upton, makes six-figures a year writing trashy romance novels under a female pen name for the masses.
Not that she begrudges him - they might be step-siblings but they've always been more like best friends. Upton considers Winnie his muse, so when he calls with terrible writer's block, desperately begging her to come up to the summer house where he's trying to meet his deadline, Winnie relents. The truth is, while she makes fun of his profession, she secretly devours all of his novels.
As Winnie tries to help Upton with his work, she finds that with every barrier they break down, they grow closer to a truth they've both been trying to hide from one another. Because while her stepbrother might want her as a muse, that isn't all he wants. And Winnie realizes, she wants him, too - more than she's ever let herself admit. Until now.
