Two friends. Two decades. One big mistake.

Nat and Zoe have always shared everything. Hopeless crushes, emergency tampons, messy sex stories, work triumphs, those days where you can't stop crying in the loos, those days where you can't stop dancing on the bar. They even share the same birthday, FFS.

The struggle is real, but they'll always have each other. Except best friends forever is a hard promise to keep. . .

Eye-wateringly hilarious, tender and true, this a story about growing up, falling apart, and the friendships that hold us together.
