Betti Bryant knows she’s not supposed to be a barista five years after graduating from college, but her life is actually super adorable—except for the part where she has to endure her ex-boyfriend’s musical rendition of their breakup at the coffee shop’s Open Mic Night every Friday. When an entire local art collection is stolen from the cafe during his performance, Betti sees her chance to persuade her panicked boss to cancel Open Mic Night, at least until the crime is solved. Instead, he announces plans to sell the beloved cafe to a real estate developer, who will demolish it. Betti believes her boss will change his mind once justice is served. So, armed with a list of drink orders from the night of the crime and the sleuthiest outfit she can find at the thrift store, she sets out to investigate the theft herself. If she fails, she’s promised her sister she’ll accept whatever non-adorable entry-level corporate job she can get, abandoning her ideals about finding her own path in life. The Coffee Station will close forever.

After years of slinging lattes, Betti Bryant is taking ownership of her life. She doesn’t need new friends or book club invitations to distract her from finding her way forward. And the unresolved situation with a guy she kissed a few weeks ago might as well stay unresolved. But there’s one distraction she is not prepared finding a murder victim on her way to work one frigid December morning. Suspicion falls on Betti’s roommate, Callista, who happens to be holding a baseball bat over the victim’s body when the police drive up. Almost totally sure Callista is innocent, Betti buys a new notebook, digs out her scrapbooking supplies, and makes the cutest murder board ever. Now, on top of holding down a job (or two) and figuring out her entire future, she’s committed to finding the real killer before any more lives are ruined—including her own.
