Genres constantly evolve, and these authors are the Mendels in the garden, mixing and matching tropes to expand the bounds of genre. SDCC special guest Matt Dinniman (The Dungeon Crawler Carl series; Operation Bounce House), Robert Jackson Bennett (A Trade of Blood), Adalyn Grace (Belladonna; The Wretched Divine), Isabel J. Kim (Sublimation), and Veronica Roth (Seek the Traitor's Son; Divergent) discuss what it takes to define—and subvert—genre tropes to create best-selling works. Moderated by Matthew Berge (Mysterious Galaxy).
