Fifteen-year-old Aiko Cassidy, a bicultural girl with cerebral palsy, grew up in Michigan with her single mother. For as long as she could remember, it was just the two of them. When a new stepfather and a baby half sister enter her life, she finds herself on the margins. Having recently come into contact with her biological father, she is invited to spend the summer with his indigo-growing family in a small Japanese farming village. Aiko thinks she just might fit in better in Japan.
