Query: The Making of a Great Book

I normally have a strict policy of paying no more than $10 million for a book, but after previewing "The Making of a Fly," I decided to remove 1.3 million other books from my wish list and free up the cash. From the first chapter ("When a Mommy Fly and a Daddy Fly Love Each Other Very Much...") to coverage of a fly's development ("Buzzing Around People's Ears: Nature or Nurture?"), Peter Lawrence details the minutiae of fly life most humans would never know. The complimentary fly swatter was an unexpected treat, although I believe the publishers may have upped the price for this reason.
