Exclusively on Audible, hilarious history for ages eight and up Did you know that most of our dinosaur fossils were discovered because two grown men absolutely hated each other? It’s true! Rivals! Frenemies Who Changed the World is a riotous audio exclusive, like if Monty Python taught your history class. Each volume of four 30-minute histories will dig into the petty name-calling and grumbling grudges that led to many of the world’s greatest advancements, all delivered with a cheeky sense of humor. Choose sides: Cope or Marsh, the jerks who discovered so many dinosaurs; Hamilton or Burr, whose rivalry fueled American politics; Queen Elizabeth or Mary Queen of Scots, who fought to rule England; Adidas or Puma, whose rivalry changed the world of sports and fashion. Kidnappings, rock fights, duels, and explosions, Rivals! shows world leaders at their absolute best and their worst, often at the same time.
