Side Note: I see my "one technique" is something you're already using on another of your blurbs - which I had read, but ... there must be some excuse I can use that doesn't sound like senility.
If possible I would try for a blurb that doesn't identify the individual stories at all - even if you are using an excerpt from one of them. Your final paragraph could simply "Five modern fairy tales, timed just right for bedtime reading, are gems that will delight the entire family." is enough if you can capture the readers attention in a brief text above it. The blurb isn't a summary, it's an appeal/attention-getter.
