I am new to anime, manga, and "light novels". I discovered the anime of the Saga of Tanya the Evil by accident, but fell in love with the story straight away. There are currently 4 light novels that the original 12 episode series is based on, with a 5th novel due to arrive sometime in 2019. The novels expand on the story in the anime, and quite simply if you love the anime, you will really enjoy the novels. I found them all to have been compulsive page turners so far, and cannot wait for the 5th volume to arrive!
