PUMSPRINA is a fascinating look at a little-known Amish coming-of-age ritual, the rumspringa -- the period of "running around" that begins for Amish youth at age sixteen. Through vivid portraits of teenagers in Indiana, Ohio, and Pennsylvania, Tom Shachtman offers an account of this aspect of Amish life as a mirror to the soul-searching and questing that we recognize as an intrinsic part of adolescence generally.
