One Perfect Couple Hardcover by Ruth Ware

Lyla is in a bit of a rut. When the opportunity arises for Nico to join the cast of a new reality TV show, One Perfect Couple, she decides to try out with him. A whirlwind audition process later, Lyla find herself whisked off to a tropical paradise with Nico, boating through the Indian Ocean towards Ever After Island, where the two of them will compete against four other couples—Bayer and Angel, Dan and Santana, Joel and Romi, and Conor and Zana—in order to win a cash prize.
