“Beautifully written and told with a watchmaker’s precision” (Stephen King), Mirrorland is a thrilling psychological suspense novel about twin sisters, the man they both love, the house that has always haunted them, and the childhood stories they can’t leave behind.

Cat lives in Los Angeles, far from 36 Westeryk Road, the imposing gothic house in Edinburgh where she and her estranged twin sister, El, grew up. As kids, they invented Mirrorland, a dark, imaginary place under the pantry stairs, full of pirates, witches, and clowns. These days, Cat rarely thinks about their childhood home, or the fact that El now lives there with her husband, Ross.

But when El mysteriously disappears after going out on her sailboat, Cat is forced to return to 36 Westeryk Road, which hasn’t changed in twenty years. The grand old house is still full of shadowy corners, and at every turn Cat finds herself stumbling on long-held secrets and terrifying ghosts from the past. Because someone—El?—has left Cat clues: a treasure hunt that leads them back to Mirrorland, where the truth lies waiting...

A brilliantly crafted story that “feels like the love child of Gillian Flynn and Stephen King” (Greer Hendricks, #1 New York Times bestselling author), Mirrorland is a propulsive, page-turning debut about love, betrayal, revenge—and the price of freedom.
