I live on the kindle unlimited books. First book I read on it was Vankara and then the second book of the series. Here is the link http://www.amazon.com/Vankara-Book-1-Saga-ebook/dp/B009P2HTDU If u like steampunk, fantasy, etc this book is pretty nice. Also they have another series called Atlantis gene which is great too. That one is more thriller but it has "aliens" and a few time portals. I was hooked. Kindle unlimited has great books that are kind of unknown but very good. If you like some YA as well or books with magic let me know bc I have a few more I could recommend from kindle unlimited.
