Kinfolks: Falling Off the Family Tree by Lisa Alther, Arcade Publishing, 241 pages. $25.
Memoirs are a tricky business these days. While they've displaced fiction in terms of sales, the market for true stories is so glutted that it's no longer sufficient to have an eccentric family or a checkered past. On the one hand, we're seeing fewer sensationalist, "I-was-a-teenage-klepto-alkie" memoirs and more thoughtful, researched ones that blend into the fields of cultural studies or historical nonfiction.
