I found What Came from the Stars by Gary D. Schmidt in the children's section of the local library. The book is said to be for 10-15 year olds. It is a Newbery Honor Winner. The book is traditionally like Tolkien---the author creates another world complete with a new language and new objects and new beings. The story is about a young boy who has just lost his mother to a horrible auto accident. The boy blames himself for the accident. He didn't say goodbye to Mom the day she died; he was angry. On his next birthday a magical necklace from another world appears in his lunchbox. He puts the necklace on and starts interacting with the strange beings from another planet.
This book is full of metaphors, similes, and hyperbole. It has a very complex storyline, plot, and list of characters. I would not use it for elementary school at all. Perhaps it would be acceptable for a middle school classroom. It would be an excellent example of the use of symbolism. The book is very enjoyable, engaging, and well written. The plot keeps moving but at times is hard to follow. There are a lot of characters to keep track of and this would make it difficult for elementary and even some middle school students. But the characters are believable and the good are caring and evil loses in the end.
