For this weekend only, the ENTIRE Awaken Online LitRPG series is on sale... for FREE! It's the only LitRPG series that I've actually enjoyed reading. The author is a far more talented writer than most in the genre.
Here's a link to the first book:

The story centers around a high school boy, but his romantic interest, Riley, grows more and more powerful over the course of the books as well, particularly in the book that centers completely around her (link below):

I highly recommend these stories if you like these sorts of stories. Jason is an anti-hero, but they are so well done that I think those who prefer more heroic characters will enjoy them as well. They are well worth grabbing for your Kindle library at no cost.
