This week on Sons Of Mjolnir, Fat Thor sits down with writer Mark Espinosa to talk all about his new book " Greetings from the Maglev." The book follows the main character, Chris Miles, in a dystopian future in which the world revolves around a magnetic super-fusion highway. Mark talks about his inspiration for the book, his experience as an indie creator as well as some good old fashion nerd talk about what he's been reading. All of this and more right here!
