Thriving on structure and organisation, Lachie's life is a tapestry of travel, surf and sea. Working and living in the breathtaking Whitsunday Islands, he finds solace in the ocean's embrace. But when carefree Irish traveller Kat crosses his path, he senses a disruption looming - a whirlwind of chaos where she treads. Kat's arrival in Australia prompts playful jokes from her family about husband-hunting, yet her desires lie in travel, work and the simple joys of life. Romance is merely a distant possibility if fate allows it. As Lachie's and Kat's worlds collide, their differences spark more than the summer heat. Will Lachie be able to deal with this, and will Kat forgive his initial distrust?
