Three weeks at sea. Two researchers. One chance to evolve. “What would Charles Darwin do?” In Charlie Bowen’s twenty-six years of life, the motto has never failed her. Until now. She’s confident the naturalist wouldn’t know what to do if he were stuck at sea with Mateo Alvarez. Throw him overboard, most likely. Participating as a scientific advisor on the SeaStar research vessel is Charlie’s dream come true. However, her fantasies never included a documentary film or cohabitation in tiny quarters with her sworn enemy. Despite her exhilaration to uncover what lurks in the ocean’s depths, she’s wholly unprepared to discover something far more revolutionary at the surface—with Mateo, it’s hard to hide the scars of her past. Worse, she may not want to. For years, she’s abided by a strict set of guidelines to keep her heart safe. Her life begins and ends with her best friend and PhD work. Yet with every lingering glance, broken rule, and stolen kiss, Charlie begins to rediscover parts of herself she once considered lost. But life at sea is not the real world—a reality that continues to haunt her, even miles offshore—and as the two move into unknown territory with each other, there’s one question that matters Can their relationship evolve into something spectacular, or are they doomed for extinction?

What happens when the cameras turn off and the PR relationship doesn’t fizzle out? It’s a question Sofía Martinez never imagined asking herself, but she didn’t anticipate fake dating her boss, either. When social media star Jett Parks offers her a new job—one with higher pay, flexibility, and a fancy title—she’s hard-pressed to say no. However, their friendship blurs lines she’d rather keep crisp and precise. Determined to make a strong impression, Sofía throws herself into planning a trip to Australia for Jett’s new docuseries, Wonder Down Under. After an out-of-context video goes viral early into their adventure, leading the internet to assume they’re dating, Sofía offers to capitalize on their moment in the spotlight. Celebrities fake relationships constantly, and if it increases ticket sales and visibility for his docuseries, all the better. How was she supposed to know that each stop would only deepen the attraction between them? There’s no employee handbook outlining the rules for PR relationships—or what to do when you accidentally fall in love. But what happens Down Under doesn’t always stay there, and Sofía must decide if what they built is real, or if it was all for show.
