What captivated me about this story was the way in which the Tear Thief is depicted, both in the language and in the illustrations. The Tear Thief is an invisislbe sprite whose task in life is to collect tears and use them to make the moon shine at night. She is not always invisible though - you can see her reflection when she is in front of water or glass or another reflective material. Also, when she collects a child's tears, the child's mood changes for the better, so really she is a transformer. When a little girl who is crying about her lost puppy sees a strange and beguiling elfin creature reflected in a puddle, the two of them start a conversation. The Tear Thief tells the girl that she collects tears and that she really wants some of hers, because they are genuine tears of sadness, and these tears are the most precious of all. The girl gives her some tears and soon afterwards, she finds her puppy. The ending is lovely and I am not going to reveal it - you have to buy the book! you will not be disappointed; it is spellbinding.
