Greyson Mann is the author of the Secrets of an Overworld Survivor series and the Creeper Diaries series, both from Sky Pony Press. He learned how to play Minecraft from his nine-year-old nephew, who proved that being a good player isn't about age--it's all about experience! Greyson still takes time to explore and have great adventures, both in the Overworld and in real life, too, near his home in Madison, Wisconsin.
