Just another boring STEM tour...or so they thought.  Add in rogue agents, explosions, and piles of 9mm shells, and it is nothing but.  Follow Sarah, a 14-year-old girl on a mission, a mission to deliver a message to the President of the United States.  Joined by Oliver, Gus, and Nick, the four embark on a journey around the world, aiming to reach Washington D.C., but their quest ultimately leads them to a surprising destination: the Dallas, Texas, Speedway.  This is one exciting ride from the most recent book by the Ridge Writer.
