An ardent (from the Latin root "to burn") collector of our books received a strangely warm package in the mail.  He said that by the time he dropped it, "the package had gotten really hot and sort of burst open on its own and was emitting a bright creepy light."  Indeed, this is not unheard of when How to Believe in Your Elf, Magic Archetypes: The Art Behind The Science Of Conjuring, and Puzzling Portmeirion: An Unconventional Guide to a Curious Destination come into close contact and are also inverted (the collector lives Down Under, you see, where everything is upside-down).  "I was guessing that there are either some pretty powerful secrets in Magic Archetypes," the collector wrote, "or perhaps these sinister books of yours really are forbidden in Australia."
