No. 36 Westeryk Road: an imposing flat-stone house on the outskirts of Edinburgh. A place of curving shadows and crumbling grandeur. But it's what lies under the house that is extraordinary – Mirrorland. A vivid make-believe world that twin sisters Cat and El created as children. A place of escape, but from what?
Now in her thirties, Cat has turned her back on her past. But when she receives news that one sunny morning, El left harbour in her sailboat and never came back, she is forced to return to Westeryk Road; to re-enter a forgotten world of lies, betrayal and danger.
Because El had a plan. She's left behind a treasure hunt that will unearth long-buried secrets. And to discover the truth, Cat must first confront the reality of her childhood – a childhood that wasn't nearly as idyllic as she remembers…
