"The Friendship Fling is fun, feisty, and sexy--I really loved it! The characters have such brilliant chemistry, and it's the perfect escapist novel to curl up with."--Emily Stone, bestselling author of Always, in December and A Winter Wish

In this delightfully charming and heartfelt debut love story, two lonely and wildly different strangers embark on a short-term friendship over one London summer--only to discover they may be something more by the time the season ends.

No one would ever call Ava Monroe a people person, which isn't ideal for a barista in a busy London coffee shop. She's sarcastic, blunt, and cynical, and her relationships are strictly no strings attached. With her best friend Josie soon leaving for a year, Ava knows she'll be all alone unless she shakes up her routine. But she can't risk bringing chance back into her carefully controlled life.

Then insufferably cheerful, country-hopping, undeniably gorgeous Finn O'Callaghan rolls into her coffee shop with a horrifying proposal --a strictly friends-only summer fling. Finn needs a local to help him complete his London bucket list, and Ava needs to reassure Josie she won't be on her own. And it's only for a few months.

To Ava's surprise, their mismatched friendship of convenience becomes oddly tolerable, and as they work their way through Finn's list and around the sun-drenched city, from rooftops and floating bars to nights at the museum, their adventures--and Finn's company--start to feel . . . nice. Incredibly, terrifyingly, dangerously nice.

Still, rules are rules--Ava has good reasons for them--and as the days get shorter, Finn's departure gets closer. Because that's the thing about summer: it always ends. Right?
