The 21 Steps by Charles Cumming is an interactive story that is told through the use of Google Maps. Readers can watch & navigate the story as it unfolds across a map of the world. About six months ago I tried making a Choose Your Own Adventure story using Google Maps, but I ultimately gave up because I didn’t want to code it all! I look forward to reading this story, and more importantly, seeing how people are able to further mash-up this concept of taking a work of fiction (or non-fiction) and putting it on a map.
