You, Again by Kate Goldbeck

Can they stop hating each other long enough to fall in love?

A commitment-phobe and a hopeless romantic clash over and over again—until heartbreak and unexpected chemistry bring them together in this clever enemies-to-friends-to-lovers debut romance.

When Ari and Josh first meet, the wrong kind of sparks fly. They hate each other. Instantly.
A free-spirited, struggling comedian who likes to keep things casual, Ari sublets, takes gigs, and she never sleeps over after hooking up. Born-and-bred Manhattanite Josh has ambitious plans: Take the culinary world by storm, find The One, and make her breakfast in his spotless kitchen. They have absolutely nothing in common . . . except that they happen to be sleeping with the same woman.
Ari and Josh never expect their paths to cross again. But years later, as they’re both reeling from ego-bruising breakups, a chance encounter leads to a surprising connection: friendship. Turns out, spending time with your former nemesis is fun when you’re too sad to hate each other—and too sad for hate sex.
As friends-without-benefits, they find comfort in late-night Netflix binges, swiping through each other’s online dating profiles, and bickering across boroughs. It’s better than romance. Until one night, the unspoken boundaries of their platonic relationship begin to blur. . . .

With sharp observations and sizzling chemistry, You, Again explores the dynamics of co-ed friendship in this sparkling romantic comedy of modern love in all its forms.
