'Iwa Young's life is high in the Maui rainforest. As a field biologist, she's happiest in company with trees and birds and waterfalls. When a developer arrives with plans for a so-called "eco resort" in the middle of a forest full of endangered species, 'Iwa puts all her energy into the fight to protect it. But a chance encounter threatens to distract her. His name is Dane Parsons, and he's a big-wave surfer from California. 'Iwa has a few unbreakable rules, and at the top of her list: never date a surfer.

Dane Parsons is part of an underground group of big-wave riders, and his connection to the ocean runs deep. When he meets 'Iwa, he can't get her out of his mind. But 'Iwa wants nothing to do with Dane until he offers to help protect her beloved forest and waterfall. Always on the hunt for the ultimate ride, Dane suddenly glimpses something even greater, but just out of reach.

In this thunderous love story, we travel deep into the Maui rainforest and hop across the globe from Hawai'i to California to Portugal, chasing waves the size of nine-story buildings--where the unthinkable is always just one breath away.
