PenguinComics.com (not to be confused with Penguin Cafe Orchestra. And yes, I do think you should go look them up) has released their first book in a line of new Random Solo Adventures books. Right out of the gate, they're going "classic" with Fantasy Dungeon.
As you can tell from the name of the book series, Fantasy Dungeon is a solo RPG book. More than just a "choose your own adventure" book, you'll need a character sheet and some dice for this game book. Take up the mantle of a heroic knight in order to save a kingdom against dragons, goblins, demons, and more. Each play through brings you new challenges and rewards.
