THE GLOOM DRAGON is a Smart Book, which is a completely new reading experience with Augmented Reality and associated free app. In the third book in the Smart Book series, you are a Swordsman. Equipped with the magical sword Rilgist and a shield, you go on an adventure in the Peasoup universe. You choose your own path through the story, where the grim Gloom Dragon threatens the small village of Tilfeldia if it doesn't get enough gold. Take part in the deep caves, fight monsters and find exciting treasures. As something new, we have designed a cool battle system that interacts between book and app. ​ The book is aimed at 8-13 year old readers and their parents. ​ A free app is included, which can be downloaded from Google Play or Apple's Appstore.
