Choose Your Own Adventure Books are a series of children's gamebooks where the reader assumes the role of the protagonist and makes choices that determine the main character's actions and the plot's outcome. Choose Your Own Adventure Books were based upon a concept created by Edward Packard and were wildly popular throughout the 80's and 90's before kind of falling off the map. Choose Your Own Adventure Books are a part of pop culture, so much so that it has led to a few lawsuits, most notably against Netflix regarding Black Mirror: Bandersnatch.
