I looked up the word 'phantasmagoria' (just to check, you understand!), and it can be a magic lantern effect, or a medley of illusive images - so, given that this book is about rather real bad dreams, it's a highly apt title for this macabre and gruesome tale.
Hazel, who is rather highly strung, is deposited with her Aunt Eugenia and cousin Isambard while her parents swan off to Egypt, and discovers a crumbling mansion with bumbling servants, together her hateful and controlling aunt and weird cousin. Having nothing to do, other than to help Isambard with his weird menagerie, she ventures into the woods - where she meets the stuff of nightmares ...
A brilliant older children's story that will entrall adults too, as well as fans of Lemony Snicket and Roald Dahl, with its mixture of horror and humour.
