Two rival marine biologists, an extremely small boat... and one very big lie.

Two rival marine biologists, an extremely small boat... and one very big lie.

Andi has learned to love her predictable life in Ohio. But when her marine biologist sister needs emergency surgery, Andi agrees to take Millie's place on the trip of a lifetime: scuba diving on the Great Barrier Reef. There's just one problem: Andi must pretend to be Millie the entire time.

But when Andi arrives in Cairns, she is horrified to learn that Hugh Harris - Millie's professional rival and extremely vocal social media critic - is also on-board. And he's very handsome. Perfect.

Somewhere between the sunsets and the beauty of the underwater world, Andi begins to question the mundanity of her life at home and whether she is capable of being the woman Hugh believes her to be.

But how can you truly fall for someone when they think you are someone else?

"I loved this sparkling and flirty take on the close-proximity trope, with warring marine biologists stuck together on a diving trip. With the sun-drenched setting this is the perfect holiday read, and I was rooting for hot hero Hugh and heroine Andi every fin-flip of the way. Emily Henry fans will love it!" - Claire McCauley

"Beach read fans will love being whisked under the sea as two marine biologists duke it out - and fall in love - on the Great Barrier Reef. Kershaw's debut is packed with heart, heat, and total escapism." - Katie Bohn
