One summer evening in 2012, during a moment of great national pride and celebration in Britain, new mum Siobhan Regan inexplicably goes missing, leaving her partner Charlie bewildered, heartbroken and bereft. Where has she gone, and why? What fate might have befallen her? This compelling, sometimes harrowing, always feel-good new novel by John Needham – part mystery, part love story – whilst completely made up, is based on an actual psychological phenomenon, a bizarre mental disorder, proving once again that truth, sometimes, can be stranger than fiction.
