A rugged island. Two people. Family secrets.

When Calla Maloney steps on the boat to Kangaroo Island, she's filled with dread. Part of it is simple seasickness but the other part is pure trepidation. She's not on a holiday but a mission: to track down her estranged brother, who she hasn't seen since her family splintered two years before.

Firefighter Sam Hunter left the island twenty years ago and has made a habit out of staying as far away as he can get. But when his father's illness forces him home, he finds himself playing bad cop to his dad and reluctant tour guide to a redhead with no sense of direction.

As Sam and Calla dig deeper into their long-buried family secrets, they discover that no one is an island and that opening up their hearts to love again might be the most dangerous thing they will ever do.
