I didn’t know bridesmaid was code for babysitter for the bride’s brother, but if that’s what my best friend needs of me for her dream wedding to go off without a hitch, that’s what I’ll do. Even if Theo Monroe has been a pain in my rear since third grade. Even if he should be responsible enough to not wreak havoc at his sister’s destination wedding.

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.

The Wheatons are infamous among the east coast elite for their lack of impulse control, except for their daughter Clara. She’s the consummate socialite: over-achieving, well-mannered, predictable. But every Wheaton has their weakness. When Clara’s childhood crush invites her to move cross-country, the offer is too tempting to resist. Unfortunately, it’s also too good to be true.

Mara, Sadie, and Hannah are friends first, scientists always. Though their fields of study might take them to different corners of the world, they can all agree on this universal truth: When it comes to love and science, opposites attract and rivals make you burn….

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.

Avery Spark is living her best life. Between her friends, her sisters, and Spark House, the event hotel her family owns, she doesn’t have much time for anything else, especially relationships. She’d rather hang out with her best friend and roommate, Declan McCormick, than deal with the dating scene. But everything changes when she is in a car accident and needs someone to care for her as she heals.

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.

I’ve got a list of people I absolutely don’t ever want to be stuck with on a boat, or a plane, or a train, and it starts and ends with the broody, grumpy, too-sexy-for-my-own good Axel Huxley. Also known as this romance novelist’s number one nemesis. The man is legendary for his mighty pen and his even mightier scowl. I tried to work together with the cocky thriller writer once upon a time, but the two of us are like vodka and good decisions. We don’t play well together.

Isabella Shay is usually a very honest person. But when she's running late for her first day at a dream job and the barista yells for "Amy" three times with no answer, she does the unthinkable. Izzy takes that PSL. But when she turns around and runs directly into the most attractive man she's ever seen, spilling the drink all over his GQ shirt and tie, she ends up having the ultimate meet-cute. Sparks fly and things feel beyond promising until he says the words, "See you tomorrow, Amy." Uh, oh-she'll definitely have to straighten him out the following day.

Kristen Petersen doesn't do drama, will fight to the death for her friends, and has no room in her life for guys who just don't get her. She's also keeping a big secret: facing a medically necessary procedure that will make it impossible for her to have children. Planning her best friend's wedding is bittersweet for Kristen - especially when she meets the best man, Josh Copeland. He's funny, sexy, never offended by her mile-wide streak of sarcasm, and always one chicken enchilada ahead of her hangry. Even her dog, Stuntman Mike, adores him. The only catch: Josh wants a big family.

Sadie Montgomery never saw what was coming . . . Literally! One minute she’s celebrating the biggest achievement of her life—placing as a finalist in the North American Portrait Society competition—the next she’s lying in a hospital bed diagnosed with a “probably temporary” condition known as face blindness. She can see, but every face she looks at is now a jumbled puzzle of disconnected features. Imagine trying to read a book upside down and in another language. This is Sadie’s new reality.

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.

I got her fired. Okay, so I’d had a bad day and took it out on a bystander in a pizza shop. But there’s nothing innocent about Ally Morales. She proves that her first day of her new job in my office, after being hired by my mother. So, maybe, her colorful, annoying, inexplicably alluring personality brightens up the magazine’s offices that have felt like a prison for the past year. Maybe, I like that she argues with me in front of the editorial staff. And maybe, my after-hours fantasies are haunted by those brown eyes and that sharp tongue.

Jack and I, we did everything backward. The day he lured me into his office - which was also the first day we met - he proposed. You'd think a guy who looked like him - a bit cold maybe, but still striking and very unattainable - would only ask the love of his life to marry him, right? You'd think he must be madly in love.

Magic-less witch Violet Maxwell wants nothing to do with alpha wolf shifter Lincoln Thorne - the man who broke her fragile teenage heart. But when the two of them are forced by arcane Supernatural Laws to find mates, Violet and Lincoln agree to fake-date their way to a fake-mating in order to conjure themselves some time. The joke’s on them.
