""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?
