Jessica Summers has always been more comfortable observing life than stepping into it. At nineteen, she spends her days behind the counter of a small café, quietly cataloging customers, routines, and emotions from a safe distance. She admires the people around her-especially Nick, an older coworker with a fragile smile, and Abby, a warm presence who makes the world feel briefly manageable-but never imagines she could be central to anyone else's story. When a series of events fractures her carefully ordered world, Jessica is forced to confront grief, responsibility, and the frightening realization that people she loves may be depending on her more than she ever expected. As her café community begins to shift, she must decide whether to remain in the background-or step forward when it matters most. Tender, funny, and quietly devastating, Brews on Summer's Heart is a modern coming-of-age novel about found family, emotional resilience, and the courage it takes to show up when life stops being safe.
