Fourth Comings, the fourth installment in the beloved, New York Times bestselling series by Megan McCafferty, captures the life of Jessica Darling as she navigates her early twenties in New York City. With a degree in psychology, Jessica works for a magazine and lives with her best friend, Hope, in a shared apartment affectionately dubbed the 'Cupcake.' Their Brooklyn neighborhood, more suited to 'breeders,' is also home to their high school friend, Manda, and Manda's 'genderqueer boifriend.'

Although Jessica's freelance work barely makes a dent in her student loans, she finds unexpected joys in babysitting her niece and the vibrant city life—full of literary parties, art openings, and downtown karaoke. Yet, it's her tumultuous relationship with Marcus Flutie that leaves Jessica most unsettled. As Marcus starts his freshman year at Princeton at twenty-three, he proposes to Jessica, giving her one week to decide. This proposal sets off a week of introspection, unexpected wisdom, and surprising revelations—including insights from a talk show shrink, a drag queen named Royalle G. Biv, and her own parents.

As Jessica considers whether to embrace her current, imperfect life or to upend it for a future with Marcus in New Jersey, she ponders with her characteristic snark and sharp insight. This pivotal week becomes the most tumultuous and memorable of her life, challenging her perceptions and the very choices that define her.
