Book Cover of Mirrorland by Carole Johnstone

Cat is a single woman living in California who returns to her childhood home in Edinburg after her identical twin sister El goes missing while sailing alone. Cat believes El is still alive because they have a “connection” to the each other, their home and the secret play area known as Mirrorland. But there’s more to this story as nothing is as it seems, memories can’t be trusted and it’s hard to know who is telling the truth. This is a fun, twisted thriller for fans of Gillian Flynn’s books.
