If Darcy Barrett hadn’t met her dream man when she was eight years old, the rest of the male population wouldn’t be such a let-down. No one measures up to Tom Valeska, aka the best man on Earth, not in looks, brain, or heart. Even worse is the knowledge that her twin brother Jamie saw him first, and claimed him forever as his best friend. Tom’s off limits and loyal to her brother, 99 percent. One percent of Tom has had to be enough for Darcy, and her adoration has been sustained by his shy kindness. And if she’s honest, his tight t-shirts.

As a third-year PhD candidate, Olive Smith doesn't believe in lasting romantic relationships—but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

Olive Torres is used to being the unlucky twin: from inexplicable mishaps to a recent layoff, her life seems to be almost comically jinxed. By contrast, her sister Ami is an eternal champion...she even managed to finance her entire wedding by winning a slew of contests. Unfortunately for Olive, the only thing worse than constant bad luck is having to spend the wedding day with the best man (and her nemesis), Ethan Thomas.

The many lives of theoretical physicist Elsie Hannaway have finally caught up with her. By day, she’s an adjunct professor, toiling away at grading labs and teaching thermodynamics in the hopes of landing tenure. By other day, Elsie makes up for her non-existent paycheck by offering her services as a fake girlfriend, tapping into her expertly honed people-pleasing skills to embody whichever version of herself the client needs. Honestly, it’s a pretty sweet gig—until her carefully constructed Elsie-verse comes crashing down.

An advertisement has been placed (again!) by the wealthy and eccentric Parloni Sisters. The salary is generous and the employers are 90 years old, so how hard could the job be? Well, none have lasted longer than a week. Most boys leave in tears. Ruthie Midona will work in Providence’s front office, and be at the Parlonis' beck and call, forever. That’s sort of her life plan. If Ruthie can run the place in her almost-retired bosses’ absence, with no hijinks/hiccups, she has a shot at becoming the new manager.

Augustus Everett is an acclaimed author of literary fiction. January Andrews writes best-selling romance. When she pens a happily ever after, he kills off his entire cast. They’re polar opposites. In fact, the only thing they have in common is that for the next three months, they're living in neighboring beach houses, broke, and bogged down with writer's block.

Hi, my name is Bree Camden, and I’m hopelessly in love with my best friend and star quarterback Nathan Donelson (so is half of America, judging by the tabloids and how much the guy dates). The first step is admitting it, right? Except, I can never admit it to him because he clearly doesn’t see me that way, and the last thing I want is for things to get weird between us. Nothing but good old-fashioned no-touching-the-sexiest-man-alive platonic friendship for us! Everything is exactly how I like it! Yes. Good. (I’m not crying; I’m just peeling an onion.)

Like an avenging, purple-haired Jedi bringing balance to the mansplained universe, Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project—a literal dream come true after years scraping by on the crumbs of academia—Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.

Felicity “Fizzy” Chen is lost. Sure, she’s got an incredible career as a beloved romance novelist with a slew of bestsellers under her belt, but when she’s asked to give a commencement address, it hits her: she hasn’t been practicing what she’s preached. Fizzy hasn’t ever really been in love. Connor Prince, documentary filmmaker and single father, loves his work but when his profit-minded boss orders him to create a reality TV show, Connor is out of his element. Desperate to find his romantic lead, a chance run-in with an exasperated Fizzy offers Connor the perfect solution.

Catalina Martín desperately needs a date to her sister’s wedding. Especially since her little white lie about her American boyfriend has spiraled out of control. Now everyone she knows—including her ex and his fiancée—will be there and eager to meet him. She only has four weeks to find someone willing to cross the Atlantic and aid in her deception. New York to Spain is no short flight and her raucous family won’t be easy to fool. Enter Aaron Blackford—her tall, handsome, condescending colleague—who surprisingly offers to step in.

Nora Stephens' life is books—she’s read them all—and she is not that type of heroine. Not the plucky one, not the laidback dream girl, and especially not the sweetheart. In fact, the only people Nora is a heroine for are her clients, for whom she lands enormous deals as a cutthroat literary agent, and her beloved little sister Libby. Which is why she agrees to go to Sunshine Falls, North Carolina, for the month of August when Libby begs her for a sisters’ trip away.

I don’t love him. I don’t even like him.I just want him. Eli Loveless was my nemesis from the first day of kindergarten until we graduated high school. Everything I did, he had to do better—and vice versa. The day he left town was the best day of my life. Ten years later, the day he came back was the worst. Now he’s my co-worker. Grown-up Eli Loveless is sexy as sin. He’s hotter than asphalt in the summer. The irritating kid I once knew is gone, and he’s been replaced by a man with green eyes, perfect abs, and a cocky smile. It’s bad that I want him. It’s worse that he wants me back.

Hallie Welch fell hard for Julian Vos at fourteen, after they almost kissed in the dark vineyards of his family’s winery. Now the prodigal hottie has returned to Napa Valley, and when Hallie is hired to revamp the gardens on the Vos estate, she wonders if she'll finally get that smooch. But the starchy professor isn’t the teenager she remembers and their polar opposite personalities clash spectacularly.

Bad luck has always followed Olivia Marshall...or maybe she's just the screw-up her family thinks she is. But when a "What are you wearing?" text from a random wrong number turns into the hottest, most entertaining - albeit anonymous - relationship of her life, she thinks things might be on the upswing.

Poppy and Alex. Alex and Poppy. They have nothing in common. She’s a wild child; he wears khakis. She has insatiable wanderlust; he prefers to stay home with a book. And somehow, ever since a fateful car share home from college many years ago, they are the very best of friends. For most of the year they live far apart—she’s in New York City, and he’s in their small hometown—but every summer, for a decade, they have taken one glorious week of vacation together.
