Mel Winterbourne’s modest map-making charity, the Orange Peel Foundation, has achieved all its aims and she’s ready to shut it down. But glamorous tech billionaire Joey Talavera has other ideas. He hijacks the foundation for his own purpose: to convince the world that the earth is flat. Using the dark arts of social media at his new master’s behest, Mel’s ruthless young successor, Shane Foxley, turns science on its head. He persuades gullible online zealots that old-style ‘globularism’ is hateful. Teachers and airline pilots face ruin if they reject the new ‘True Earth’ orthodoxy. Can Mel and her fellow heretics - vilified as ‘True-Earth Rejecting Globularists’ (Tergs) - thwart Orange Peel before insanity takes over? Might the solution to the problem lie in the 15th century? Using his trademark mix of history and satire to poke fun at modern foibles, Simon Edge is at his razor-sharp best in a caper that may be more relevant than you think.
