Magic always comes with consequences and costs, whether it's the sacrifice of years spent studying or a literal, physical sacrifice. How do characters get (or lose) their magic? How can the consequences of magic ramp up the suspense? Acclaimed fantasy novelists Tomi Adeyemi (Children of Blood and Bone), Stephanie Garber (Legendary), Sara Hanover (The Late Great Wizard), Daniel José Older (Dactyl Hill Squad, Star Wars: Last Shot), Sam Sykes (Seven Blades in Black), and Sabaa Tahir (A Reaper at the Gates) discuss magic systems, magic spells, and the price of magic with David Canfield (Entertainment Weekly).
