A chillingly charming book that hold the possibility of mystery for children and adults. The book is a dare of sorts, a temptation both visual and metaphoric. It alludes to danger and salvation, to curiosity and fear, to wonder and to faith. Be aware - it may scare your children - but it may delight them. My three year old laughs out loud, and chants the rhythmic refrain with me as I read. It is a mysterious poem, with beautiful illustration.
