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.

Rue Siebert might not have it all, but she has enough: a few friends she can always count on, the financial stability she yearned for as a kid, and a successful career as a biotech engineer at Kline, one of the most promising start-ups in the field of food science. Her world is stable, pleasant, and hard-fought. Until a hostile takeover and its offensively attractive front man threatens to bring it all crumbling down.

Viola Bowen has the chance of a lifetime: to design a video game based on her all-time favorite book series. The only problem? Her co-lead is Jesse F-ing Andrews, a.k.a. her arch-nemesis. Jesse has made it abundantly clear over the years that he wants nothing to do with her–and Viola has no idea why. When their bosses insist a wintery retreat is the perfect team-building exercise, Viola can’t think of anything worse. Being freezing cold in a remote mountain lodge knowing Jesse is right next door? No, thank you.

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.

Misery Lark, the only daughter of the most powerful Vampyre councilman of the Southwest, is an outcast—again. Her days of living in anonymity among the Humans are over: she has been called upon to uphold a historic peacekeeping alliance between the Vampyres and their mortal enemies, the Weres, and she sees little choice but to surrender herself in the exchange—again...

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….

Scarlett Vandermeer is swimming upstream. A Junior at Stanford and a student-athlete who specializes in platform diving, Scarlett prefers to keep her head down, concentrating on getting into med school and on recovering from the injury. She has no time for relationships. Swim captain, world champion, all-around aquatics golden boy Lukas Blomqvist thrives on discipline. It’s how he wins gold medals and breaks records: complete focus, with every stroke. On the surface, Lukas and Scarlett have nothing in common. Until a well-guarded secret slips out, and everything changes.

Gigi Graham has exactly three goals: qualify for the women's national hockey team, win Olympic gold, and step out of her famous father's shadow. So far, so good, except for two little things. Fine—a little thing and a big, grumpy thing. She needs to improve her game behind the net, and she needs help from Luke Ryder. Ryder is six-foot five, built, opinionated, rude . . . and sexy as hell. But he's still the enemy.

Adalyn Reyes has spent years perfecting her daily routine: wake up at dawn, drive to the Miami Flames FC offices, try her hardest to leave a mark, go home, and repeat. But her routine is disrupted when a video of her in an altercation with the team’s mascot goes viral. Rather than fire her, the team’s owner—who happens to be her father—sends Adalyn to middle-of-nowhere North Carolina, where she’s tasked with turning around the struggling local soccer team, the Green Warriors, as a way to redeem herself.

Mackenzie Carter has had some very bad dates lately. Model train experts, mansplainers, guys weirdly obsessed with her tail—she hasn’t had a successful date in months. Only a year out of residency, her grandmother’s obsession with Mackenzie finding the perfect mate to settle down with threatens to drive Mackenzie barking mad. Out of options, it feels like a small thing to tell her grandmother that she’s met someone. That is, until she blurts out the name of the first man she sees and the last man she would ever date: Noah Taylor, the big bad wolf of Denver General.

Melody Gallard may be the daughter of music royalty, but her world is far from glamorous. She spends her days restoring old books and avoiding the limelight (one awkward tabloid photo was enough, thanks). But when a producer offers her a lot of money to reunite her mother’s band on live tv, Mel begins to wonder if it’s time to rattle the cage, shake up her quiet life…and see him again. The only other person who could wrangle the rock and roll divas.

Anastasia Allen has worked her entire life for a shot at Team USA. It looks like everything is going according to plan when she gets a full scholarship to the University of California, Maple Hills and lands a place on their competitive figure skating team. Nothing will stand in her way, not even the captain of the hockey team, Nate Hawkins.

Sasha has had it. She cannot bring herself to respond to another inane, “urgent” email or participate in the corporate employee joyfulness program. She hasn’t seen her friends in months. Sex? Seems like a lot of effort. Even cooking dinner takes far too much planning. Sasha has hit a wall. Armed with good intentions to drink kale smoothies, try yoga, and find peace, she heads to the seaside resort she loved as a child. But it’s the off season, the hotel is in a dilapidated shambles, and she has to share the beach with the only other occupant: a grumpy guy named Finn.

What does one do when they completely blow an interview? If you're me, you pick up a one-night stand with the most gorgeous man you've ever seen.. That's right, after a lousy interview that could have changed everything for me, I headed over to the local small town bar to sulk when the one man I shouldn't want walked in. And when my friend convinced me to take him back to my hotel room, I didn't think about it, I just did it . . . well, I did him.

Daphne always loved the way her fiancé Peter told their story. How they met (on a blustery day), fell in love (over an errant hat), and moved back to his lakeside hometown to begin their life together. He really was good at telling it…right up until the moment he realized he was actually in love with his childhood best friend Petra. Which is how Daphne begins her new story.
