A mixture of two stories, but it works quite well. I like the motif of an unlikely hero in fairytales: you can be ridiculed for having artistic leanings or different interests compared to others, but it's the character that determines one's fate. Sure, Perrin wouldn't have survived without the magic whistle, but he was rewarded with it precisely because he was brave and wanted to make his mother happy. Unfortunately, Sanderson's illustrations in this one were not for me. I think she tried to make them look like tapestries, but they're not quite there, just a little less detailed than her normal work.
