Like some lost chapters from the Celtic folk tradition, Grimoire tells stories of ordinary people caught up, suddenly, in the extraordinary: tales of violence, madness and retribution, of second sight, witches, ghosts, selkies, changelings and doubles, all bound within a larger mythology, narrated by a doomed shape-changer - a man, beast or god. A grimoire is a manual for invoking spirits. Longlisted for the Highland Book Prize 2020, from the author of "The Long Take".
