The Worst Best Man

Written by Lucy Score in 2024, The Worst Best Man focuses on Aiden Kilbourn, New York City’s hottest billionaire bachelor. Aiden finds his dislike of long-term relationships challenged when he acts as the best man at a wedding and encounters the working-class Frankie Baranski, the witty and confident maid of honor. As the two engage in a wide variety of escapades and fall in love, they must both grow to learn how to be supportive partners to one another.

Score’s first novel, Undercover Love, had modest success, but she eventually became a “BookTok” sensation, and her subsequent novels continued to gain traction until her novel Things We Never Got Over became the first of her titles to make the New York Times Best Seller list. To date, she has sold millions of novels worldwide, and her works have been translated into 29 languages.
