Turns out that reading nothing but true crime isn’t exactly conducive to modern dating-and one woman is going to have to learn how to give love a chance when she’s used to suspecting the worst.

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 (he may dress business casual by day, but at night he’s clearly up to something). 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.
