"When Jeremy visits his twin cousins Jack and Flash in Oklahoma, he gets a big surprise: they're storm chasers! They live in a region called Tornado Alley, an area with more tornadoes than anywhere else in the world. Jack and Flash travel around Tornado Alley looking for tornadoes, and Jeremy is coming with them on their next mission. In Twister! Jeremy and his cousins encounter giant hailstones, awesome lightning, and funnel clouds, but will they get to see a tornado face-to-face? And will they get sucked up into its trail of destruction?"--Publisher's description.
