Hello, I'm Harper, and I guess that I'm shamelessly self-promoting myself around the internet
"Heroes & Villains" does contain m/m romance, though most of the "action" takes place off-screen. It's mostly the building up of the relationship between Vereint Georges and Warrick Tobias as they take on the roles of archenemies and eventually become something more.
There's plenty of action, though, from Mindless Minions of Mayhem (MMM), alien robots, and a growing terrorist organization, the Darksters.

Here's the "back of the book" description: As the superhero Starburst, Vereint received only derision and mockery. All his heroic endeavors resulted in nothing but humiliation. No matter how hard he tried, the world could only see him as a joke.
Eventually he was pushed into the life of a supervillain. He changed his name to Darkstar and began his reign over Megacity. He was unstoppable... yet somehow he managed to fall into myth and legend.
"Heroes & Villains" details the budding relationship between Vereint Georges and Warrick Tobias as they explore the idea of a superhero and a supervillain falling in love. It is a story of friendship, affection, romance, and super battles.
