I'm not gonna lie, I picked up Snow in Summer because it was on the new releases shelf and it's by Jane Yolen. And it was exactly as I expected: a fairy tale base placed into a new time period. Yolen places Snow in Depression Era America. The magic of the fairy tale is present, but not overwhelmingly unrealistic, just right where you want it.
Snow in Summer is an enjoyable young adult novel and suitable for any young adult reader. It wasn't super by any means, but a cute little read. It's a little odd, though, that this Snow is familiar with the story of Snow White and doesn't ever put the two together; I just wanted her to be a little smarter. I expected a little more from Yolen, but I still recommend this book. It's a fun, quick read.
PS There's a bear named Ursa! :)
