Tully Larson has loved tropical storms since he was a kid and spent his summers with his dad in the wilds of Kakadu National Park. He's happiest outdoors, a rough and ready kind of guy who loves the power of Mother Nature and chasing the thrill of electrical storms every chance he gets.

Jeremiah Overton, a fulminologist from Melbourne, chases storms for a whole different reason. Lightning has shaped his entire life and he's driven to study it, to understand it, so heading to Kakadu in the middle of the storm season is a logical thing to do. After all, the Top End is the lightning capital of Australia.

Tully wasn't sure how a week at his remote bunker with an academic type would pan out. And Jeremiah didn't expect much from the storm-chasing cowboy who volunteered to take him.

But both men know all too well that when opposites attract, lightning strikes.
