Mia Baron thrives on routine: early mornings slinging coffee, quiet nights in her tiny San Francisco apartment, and absolutely no surprises. But when a misdelivered package—and its wildly unexpected contents—throws her into the orbit of her infuriatingly charming neighbor, Mia’s carefully controlled world is turned upside down.

Enter Griffon Scott, the vibrant and annoyingly attractive new neighbor who seems hell-bent on invading Mia’s peace. Between blasting music and late-night activities, she’s impossible to ignore. What starts as an inconvenient clash soon gives way to a connection Mia never saw coming, one that’s equal parts frustrating and thrilling.
