Naomi and Luca have been pen-pals since fifth-grade. Well, more like bitter rivals caught in an epic battle of insults and verbal jousting. But what starts as a hilarious chain of hate filled letters, slowly develops into a friendship spanning coasts and years. That is until one day, 12 years later, when the letters suddenly stop. It’s been two years since Naomi last heard from Luca. Two years since the letter that changed everything. But when a new envelope turns up out of the blue at her desk at the local news station, Naomi is determined not to let Luca have the final word.

Eleanor Lark is an upbeat illustrator plagued by headaches and unruly strawberry blond hair. After a grueling cross-country flight, she blacks out cold. The brooding stranger who sat next to her grumping his way through the flight catches Elle as she falls. Neither expects the sweet chaos that happens next. August Marshall is stonehearted, insanely rich, and a master of corporate cleanups with major baggage of his own. The last man alive who needs a media frenzy after his airport heroics steal headlines. But August has a plan—ask Elle to marry him so their trouble disappears.

Lizzie Rose knows what she likes and likes what she knows. Her role at the London Museum is more than a job, it’s her safe place and her passion. So when Lizzie is passed over for a chance in a lifetime opportunity in favour of her ex-boyfriend and fellow Egypt nerd Friedrich Klein, her heartbreak over their relationship pales into insignificance compared to her sadness at losing the project. Best friend Colette thinks an evening of cocktails is just the medicine for a broken heart, and meeting charming, but very much ‘not her type’ Finn Bryson at the bar puts a smile on Lizzie’s face too.

As an estate agent, Alex’s job is to create happy-ever-afters. It’s just a shame she can’t work the same magic on her own life. Her long-term boyfriend Thomas still lives with his mother, and her hopes of them taking the next step are dashed when he announces he’s spending all his savings (savings she’d quite hoped he’d want to put towards their future home) on an ‘artist retreat’ in San Francisco.

School reunions: the perfect opportunity to catch up with old friends, dazzle old foes and basically show everyone that your life could not be going better. But for Lucas O’Rourke and Posy Edwins this isn’t quite the case. Lucas is about to lose his business unless he finds an investor fast, and Posy’s father has cut her off financially, just when she needs to get to Hawaii. And a reunion is the worst moment to come face-to-face with your rival. Ten years ago, they hated each other; what could have changed since then?
