I don't have I-devices, so I don't often check Itunes, but I did happen to look tonight and The First Galactic Princess -- a Bedtime Story, has a solid 4-Star rating. Of the six individual ratings, four are 5-Stars. If you have a very young daughter (or son) who likes bedtime stories and has a sense of wonder, give it a look.
