But Coke and Pepsi McDonald aren't in the clear just yet! Before they reach the finish line, the twins will be:
Abducted by aliens,
Trapped with a venomous snake,
Pushed through a deadly turbine, and
Thrown into a volcano.
Craziest of all, their parents might finally believe them!
Will the twins make it back home to California in one piece, or will they fall off the top of the Golden Gate Bridge? It's all coming to an end with this fifth book in the Genius Files series. You'll have to listen to believe it!

Funny, interesting, satisfying.<br />
I love how the coke and pep continue to see weird places and the parents never find out the badges are trying to kill them.
