Lauren Fox is the bookkeeper for Cold World, a tourist destination that's always a winter wonderland despite being located in humid Orlando, Florida. Her coworker, Asa Williamson, is all about finding ways to enliven his days at Cold World. When the owner asks Lauren and Asa to propose something to raise more revenue, their rivalry heats up as they compete to come up with the best idea. But the situation is more dire than they thought, and it might take these polar opposites working together to save the day. If Asa thought Lauren didn't know how to enjoy herself, he's surprised by how much he enjoys spending time together. And if Lauren thought Asa wasn't serious about anything, she's surprised by how seriously he seems to take her.

PhD candidate Phoebe Walsh has always been obsessed with true crime. She's even analyzing the genre in her dissertation --- if she can manage to finish writing it. It's hard to find the time while she spends the summer in Florida, cleaning out her childhood home, dealing with her obnoxiously good-natured younger brother, and grappling with the complicated feelings of mourning a father she hadn't had a relationship with for years. It doesn't help that she's low-key convinced that her new neighbor, Sam Dennings, is a serial killer. It's not long before Phoebe realizes that Sam might be something much scarier --- a genuinely nice guy who can pierce her armor to reach her vulnerable heart.
