The Summer Island Swap by Samantha Tonge

Sometimes the best holidays are the ones you least expect…

After a long and turbulent year, Sarah is dreaming of the five-star getaway her sister has booked them on. White sands, cocktails, massages, the Caribbean is calling to them.
But the sisters turn up to tatty beaches, basic wooden shacks, a compost toilet and outdoor cold water showers. It turns out that at the last minute Amy decided a conservation project would be much more fun than a luxury resort.
So now Sarah’s battling mosquitos, trying to stomach fish soup and praying for a swift escape. Life on a desert island though isn’t all doom and gloom. They’re at one with nature, learning about each other and making new friends. And Sarah is distracted by the dishy, yet incredibly moody, island leader she’s sure is hiding a secret.
