A brilliantly funny, romantic and effervescent read, If We're Not Married by Thirty is the irresistible new novel from the bestselling author of The Bucket List to Mend a Broken Heart and It Started With a Tweet.

Lydia's not exactly Living Her Best Life. She never imagined she'd be here at thirty - newly single, a job that's going nowhere and her friends all winning at life when she's still barely taking part. So she jumps at the chance of a free holiday and jets off to sunny Spain. Then, out of the blue, she bumps into her childhood friend, the handsome and charming Danny Whittaker. She's always had a crush on him and they soon enter into a passionate holiday romance. But this relationship could be more than just a fling. Years ago they made a pact that if they were still single when they turned thirty they would get married. But noone really follows through on these pacts . . . right? Could Lydia's back-up man really be her happy ever after?
