Ember's End by S.D Smith
Looking through my ebook library, I saw one series that I had started but have yet to finish. When I first got my Fire Tablet, I looked through the free-to-read books, and this series caught my eye. Although a children's series, it provided me with adequate stimulation before heading to bed. I'm not a fan of rabbits. I prefer their predators, birds (which are the villains in this story), but the protagonist won me over, and so did the plot. Mainly, the idea of rabbits with swords was entertaining enough.
