This HaBO comes from Elizabeth, who wants to locate this romance:

I’m looking for a Harlequin Presents, enemies to lovers romance that is set in Australia.

The heroine is engaged to a guy her whole family hates, and she eventually dumps him when it becomes clear he’s a jerk. I feel like the scene where she realizes she can’t marry her fiance is set on a yacht. Meanwhile, the hero is visiting the heroine’s brother, and convinces her that she should just marry him on the originally scheduled wedding day. I think this scene happens while they are swimming.

There is a scene where the main couple visit the hospital and her dad bluntly asks her if she is sure she wants to do this. I think they honeymoon in Mexico and Vegas.

It’s driving me crazy that I can’t remember this book!

Let’s HaBO!
