I did it! I changed the covers of the Blue Mountain series. The cover here will be the cover for the first box set, which should be published at the end of April. I've now uploaded the first three books, Summertime Blue, My Blue Heaven and Kind of Blue on Amazon and also released them in KU.
Below are the new covers for these books and, as a sneak preview, the covers for the next three books in the series. I'm not sure which one of Out of the Blue or A Spark of Blue I will publish first, or when, but I will let you know.
