Wally the Web Wizard — Michael D. Young

Wally was your typical medieval wizard, pointy hat and all, until one day, he cast a spell to gaze into the future. Then he makes a connection...with the Internet! A whole new world of social media, electronic mail, and more awaits him, but he soon discovers that the wonders of the Internet come with dangers, from predatory dragons to actual Internet trolls! Fortunately, Wally has a guide, the gallant Sir Brows, to help him navigate the perils of cyberspace, before Wally brings the whole castle down around him.
