This unnerving tale begins in 1979 and reaches its turbulent conclusion around Halloweeen, 2015. Because every nine years, on the last Saturday of October, a 'guest' is summoned to Slade House. But why has that person been chosen, by whom and for what purpose? Born out of the short story David Mitchell published in 2014 and inhabiting the same universe as his latest novel The Bone Clocks, this is the perfect book to curl up with on a dark and stormy night. Prepare to be chilled.
