This fantasy series is a bit on the dark side, dealing with souls trying to escape from death, and the main characters "job" to return them. However it is a fascinating story, really well written and a riviting read. The first book can stand alone, but with all three together they are so good that you become disappointed when you get to the end that its over..... and since I couldn't put any of them down, that happens fast. Would probably not give this to lower grade elementary kids, but great for 5th grade up.... and as engrossing for adults like me. The main characters in the story are strong female ones, however I think that this would be a good read for both sexes. This was so good, that having told all my friends of its merits, am off to try some more of his other writings.
