Air elemental Sylphie Seaton has the perfect job—chasing twisters. Every year she and her team of elemental scientists hit the road during tornado season to track the elusive weather phenomena in order to collect new data.

Things are about to get complicated when Eric Gage, an extreme photojournalist, comes along for the ride. He's human, and completely ignorant about the supernatural world. Sylphie can't decide whether to find the man charming or infuriating, a tension that's tested when they go up against one of Nature's most volatile forces.

For something's off with this season's twisters. There's an eerie echo in the wind, and the most destructive weather events seem a little too targeted. It's impossible to control a tornado...or so she thought. But when Gage stumbles upon an unnatural pattern and a shady corporation, Sylphie is drawn into a deadly conspiracy that could not only expose elementals, but cost the lives of everyone she holds dear.
