Book 1 of this series. This series I saw recommended a lot and I was not disappointed. This is one of the few in the LitRPG genre that I would recommend to the YA audience. If you’re a fan of Seth Ring or Ivan Kal or Vasily Mahanenko you’ll love this book. Very well done. The magic system is complex and detailed. The worlds are vividly written. The characters pop off the page. If you’re on the fence, give this one a try.
