1. "Flaubert‘s Parrot" had paperback sales of 63,000 and hardcover sales of over 20,000.
2. Romentic novelettes are based on the same basic formula as the traditional heterosexual romance (which, incidentally, accounts for 4' per cent of all US paperback sales). The plot must never deviate — two people meet, they fall in love, complications and jealousies ensue, but they are eventually resolved and by the end of the story the lovers are heading for marriage and happiness ever after.
