Have you read her Fairy Tale series? I haven't but was thinking of starting it. The covers make it look rather middle grade but I don't think it is from the excerpts.

Wasn't aware of a second series by her. TBH, this series has covers that could also work on a younger audience too, so they could be alright.

Oops, should have given the booklikes link to the first book of other series: http://booklikes.com/a-fairy-tale-shanna-swendson/book,13166638

(And I've been patting myself on the back for being good about inserting booklikes book page links instead of Amazon, goodreads, etc.)
