MIRRORLAND

When her identical twin sister goes missing, a Scottish writer living in Los Angeles returns home.

On Sept. 5, 1998, identical twins Ellice and Catriona show up at Edinburgh's Granton Harbour at dawn, covered in blood and badly beaten, seeking passage aboard a pirate ship. That was the day their second life began. Fast-forward almost two decades and the now 31-year-old twins are estranged. El is married to their childhood friend Ross and living in Edinburgh in the house on Westeryk Road where the twins had lived with their mother and grandfather. Cat is single and living in a condo overlooking the Pacific Ocean in Southern California. When El goes missing while sailing, Ross calls Cat, and she rushes back to Edinburgh. Cat is convinced that El is fine because she has an unshakable belief that she would have felt it if her sister were dead, and the cruelty of going missing is exactly what she would expect from El. Returning to her childhood home stirs up long-buried memories for Cat. Front and center among those are the endless hours the pair spent with Ross and a host of imaginary friends in Mirrorland, their name for the secret covered alley next to the house that was the setting for their childhood adventures on the high seas, in the Wild West, and at the prison from The Shawshank Redemption. Author Johnstone has created a dark, twisting thriller that explores the pitch-black corners of people’s minds; how good and bad, love and hate, terror and joy can co-exist; and how childhood memories can be rewritten with time as the lines between imagination and reality are blurred. Fans of Gillian Flynn's creeping dread and Liane Moriarty's nuanced morality and complex relationships should love this book.

An enthralling thriller.
