Toko Fukami thought she had settled on what she wanted in life: to hang out with her four best friends in their small seaside town, and to eventually become a professional glassblower working in her family's glassworks. But now two things have happened that may change her destiny forever. First, she's seeing things. When she looks into reflections in glass, sometimes she catches glimpses of things that haven't happened yet. And then a new boy, Kakeru, transfers into town, claiming that a voice from the future led him to her. Suddenly Toko is re-evaluating everything she thought she knew, from the proper care of her school's chickens to how she really feels about each of her friends. Get ready for an amazing summer that stands between the possibilities of the future and the memories of the past as six young people come of age in GLASSLIP.
