The Great Flying Adventure Sequel to "Adventure Bike Club & the Tire Giant"
Amanda and Quentin fly to an alien world where Quentin competes in a brutal tournament to save the Earth from invasion, but Amanda falls for the enemy team captain, and things become terribly complex. "Purple Nazis" control half the alien world but are unable to topple the legitimate government even after years of struggle. All will be decided in a final flame ball game. Eddie Hawkes, grown to maturity after 5 years of alien time, calls Quentin back to help in the great game. Quentin is only three weeks older in Earth time and is the smallest team member. His human speed and coordination may or may not make up the difference. Political intrigue, kidnapping, and mysterious alien beings add to the fun.
