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.

Jeremiah Overton is now in charge of Darwin’s Bureau of Meteorology, and his storm chaser boyfriend, Tully Larson, couldn’t be happier. For Tully, it means watching summer storms with the love of his life but for Jeremiah, it means relearning everything on equipment that’s older than he is.

But summer storms also mean it’s cyclone season. While Tully’s no stranger to tropical storms and the occasional cyclone, for Jeremiah, it’s a first.

As Tropical Cyclone Hazer bears down on the city, Jeremiah and Tully prepare to stay behind. Jeremiah knows what to expect, theoretically, but living through it is a different story.

If they live through it at all.

Without a working office, Jeremiah is tasked with repairing the automated weather station on Oxley Island. It’s remote, only accessible by boat, and with there being a good chance of crocodiles, he’s dreading it.

Tully, on the other hand, can’t wait.

With a boat licence, his dad’s boat, and two days alone with Jeremiah—and with thunderstorms likely—to Tully, it’s another perfect adventure.

But their plans go awry when Jeremiah’s research gets far too close for comfort. Thirty years ago, the day his life was touched by lightning, he was changed forever.

It’s about to change again, only this time he’s determined to set things right.
