The Different Girl by Gordon DahlQuist

Product Description A timeless and evocative debut for contemporary and sci-fi fans Veronika. Caroline. Isobel. Eleanor. One blond, one brunette, one redhead, one with hair black as tar. Four otherwise identical girls who spend their days in sync, tasked to learn. But when May, a very different kind of girl—the lone survivor of a recent shipwreck—suddenly and mysteriously arrives on the island, an unsettling mirror is about to be held up to the life the girls have never before questioned.
