In the 12th book of the Hamilton Troll Adventures, Hamilton and Starlit have a Big Race. They run and swim, climb and fly – but in the end there is a winner and a loser and the loser is not being a very good sport. In the end this is a good message for all children:
“Win or Lose, you’ll always succeed,
so long as you do your best!”
