Certain books are like good friends, others mere aquaintances. Still, some books defy categorization, and, like a stranger willing to make and sustain eye contact, are themselves uncertainties. In honor of such books (not counting poetry, of course) that neither refuse nor elect to wear their hearts on their front covers, we're happy to share one "weird" book a month, which we're sure won't be in stock nearly as long as in our heads.
