They say you can never go home again, and for Persephone Fraser, ever since she made the biggest mistake of her life a decade ago, that has felt too true.

Harriet and Wyn have been the perfect couple since they met in college—they go together like salt and pepper, honey and tea, lobster and rolls. Except, now—for reasons they’re still not discussing—they don’t. They broke up five months ago. And still haven’t told their best friends.

Lucy Hutton has always been certain that the nice girl can get the corner office. She's charming and accommodating and prides herself on being loved by everyone at Bexley & Gamin.

Trapped in a shared office together 40 (ok, 50 or 60) hours a week, they've become entrenched in an addictive, ridiculous never-ending game of one-upmanship.

Minnie Cooper knows two things with certainty: that her New Year's birthday is unlucky, and that it's all because of Quinn Hamilton, a man she's never met. Their mothers gave birth to them at the same hospital just after midnight on New Year's Day, but Quinn was given the cash prize for being the first baby born in London in 1990 - and the name Minnie was meant to have, as well. With luck like that, it's no wonder each of her birthdays has been more of a disaster than the one before.
