Luca Wexler has grown up in a world where superheroes and villains are a staple of the nightly news. Now at seventeen years old, with eight years of superhero training, a scrappy attitude, and a mountain of sass—he figures that’s everything he needs to make it big as The Avalon Knight. (Behind his dad’s back.) Even though his trainer keeps him on the streets to break up muggings or the occasional burglary, he somehow gets thrust into a supervillain crisis! (Okay, he might have accidentally-on-purpose thrust himself into it.) A genius hacker and social media celebrity—known only as The Gentleman—is at the center of a conspiracy of blackmail, extortion, and exploitation. And seeing as how America’s A-List superheroes are MIA, Luca’s the only one who can do anything about it. He's sure that he's ready. He’s used to picking fights with bigger guys (he’s smol but mighty), but as the situation turns deadly, Luca begins to get the feeling that he might (absolutely) be in over his head.
