Ten-year-old Kai is given a magical crystal doorknob by his grandfather that enables him to travel through space and time to see future events in his life. The further along he goes, the less he feels like he's seeing into his future, but more that he is living life as most people do; all too quickly. Both poignantly sad and zany, Pulitzer Prize finalist Jordan Harrison expands on the notion that life is too short to miss any moment of it.
