This book grips the reader right from the start, and from the preface, the introduction and the cover, it suggests that it will not let you go until the end. It also feels like a claustrophobic's worst nightmare, which has become Hannah's reality. The tiny space she needs to live in is not even the worst of her issues, as the shadowy figure of 'him' haunts her very existence as conflicting thoughts race through her mind daily. Chilling, gripping and definitely worth a read.
