What a delightful book.
My review is slightly coloured since Neil Gaiman read this to me live at a signing event, and his pacing, accent, and humour sealed the deal for me.
Regardless, give this a whirl. The illustrations are zany and perfect, and the story will entertain adults and kids alike.
One recommendation: savour it. Read it slowly. Read it out loud. Revel in the beauty of the language and the story.
