Secretly Rosie Strange has always thought herself a little bit more interesting than most people - the legacy her family has bequeathed her is definitely so, she's long believed. But then life takes a peculiar turn when the Strange legacy turns out not just to be the Essex Witch Museum, but perhaps some otherworldly gifts that Rosie finds difficult to fathom. Meanwhile Sam Stone, Rosie's curator, is oddly distracted as breadcrumb clues into what happened to his missing younger brother and other abducted boys from the past are poised to lead him and Rosie deep into a dark wood where there lurks something far scarier than Hansel and Gretel's witch?
