On Viking Seas is the third book in the Forerunner Series by Jay Veloso Batista.
I would definitely recommend starting this series from the beginning, it took me a few chapters to catch up with the story and I will definitely go back to book one to read all the bits I have missed.
As you would expect from the title, this story is packed full of adventure. There is a lot going on and the author really keeps the reader on their toes throughout by adding twists and turns along the way.
I particularly enjoy that the book is based on actual historical events, and the author really shows off their Viking knowledge which adds so much detail and passion. Great read, especially if you’re looking for something a bit different.
