Bestsellers

According to the Lulu Titlescorer,

• The Coming of the Fairies has a 63.7% chance of becoming a bestseller
  
• The Secret Common-Wealth has a 69% chance
  
• The Madness of Kentaurs has a 35.9% chance
  
• The Stolen Child has a 41.4% chance
  
• Three Sisters has a 14.6% chance
  
• and Bunk has a 31.7% chance.

Of course, only the first three have actually been written (and only the first one revised). Scientific bestseller projection for books not even written yet! Amazing!
