This is something that we haven't ever seen before now, which makes it worth the price just to see how well it works, but it turns out that Demon: Interface actually works WELL! The stories offer views into the world of these creatures in a way that the game's books only hint at, and that's what great fiction adds to your chronicle. The mechanics that complement each story won't be equally useful for every troupe, but they each give insight into not just what happened in the story and show a peek at WHY it occurred.
For the price of one book, this book pulls double-duty, and you won't find that either one suffers for the other!
