This was a BookBub recommendation - being the first of a series it was free on kindle. (yes i read on my phone too). It over 500 5 star reviews on Amazon and 888 4 star & over reviews on Goodreads. From the Publisher:
I love dystopian novels, which is of course why I chose this one. It's central idea is refreshingly new, with a little nod to writers like Margaret Atwood and Sherri S Tepper. What kept me reading was the characters with their intertwined story lines. This is a well written book with a lot more depth than one would expect at first glance.
I give it 4 stars and must add that it was so good I bought the rest of the series. I've finished them all now and can't wait for the final novel to come out. What I can saw about the rest of the books in the series is that the story lines don't always go where you'd expect - how refreshing!
