My 3 1/2 & 21 month old sons love this book and insist I read it to them evry night before bedtime. The artwork is attention grabbing and the prose has a nice cadence. Of course I throw in my own personal sound effects for the witches, ghosts, werewolf & Frankenstein. This just gets them giggling like crazy. This book is not too scary for the littlest kids, because if you look closely, there's almost always a 'hidden' item which helps explains the 'spooky' stuff. You can point this out as you go along. The surprise ending is quite nice too. I highly reccommend this book for kids 18 months to 5 years.
