Crypto Love by Stephanie Beck

Sidekick becomes hero to save superheroes everywhere. Chris, aka Crypto Man, loves being a sidekick—especially the 'kicking' part. When he returns to his boyhood home to search for clues about a recent increase in villains coming from the area, he finds himself face to face with a beautiful woman, and for the first time he has a shot at being the lead hero. Penna Banena always wanted to be a hero. She even gave up modeling to join The Warden's School for Superheroes. When she discovers it's not only a scam but is providing inside information to villains, she stays on to gather enough evidence to take the whole ring down. Crypto Man's appearance throws her plan for a loop. He's blunt, tough, and everything she's ever hoped for in a man. And although romance has to take a backseat to defeating the bad guys, if Penna has her way Crypto Man's world will never be the same.
