Devan Montgomery is forced to go to Hawaii and isn't happy about it ... until she meets an attractive Hawaiian lifeguard named Kai. The moment their eyes meet it's evident that Kai and Devan share a soul-deep connection.

As luck would have it, Kai is really Kale Iakona, a pain in the ass from her past. Despite a tumultuous history, their feelings are too intense to deny and their animosity quickly subsides.

They are on the fast track to happily ever after when fate steps in and rips them apart. Eventually, they end up married to other people, but remain close.

After a falling out, Devan and Kale don't speak to each other for three years, until they're asked to be in the wedding party for their best friends' wedding.

Can they go back to being friends or will the threat of overwhelming temptation force them to say "Aloha" to true love forever?
