Eddie Hertz is a 12-year-old genius who patrols the streets of Nirvana, hoping to foil the schemes of the evil Mephisto. Being small for his age, Eddie relies on a Batman-style gadgets belt and acrobatic skills as well as street smarts and ingenuity. Eddie has a dream, to become like Damocles, Nirvana's great superhero. To accomplish that goal, Eddie invented a device that theoretically will endow him with superpowers, but using it on himself could be dangerous, maybe even fatal, so he doesn't have the nerve to try it. When Mephisto unleashes an earthquake machine to terrorize the city, Eddie gains a surprising ally - his quirky eight-year-old sister, Samantha, who comes up with an unexpected way to help in the frantic battle to prevent the impending destruction. Working as a team, the siblings fight Mephisto in a race against time to save Nirvana and the world from devastating earthquakes, all the while receiving advice from a computerized version of Damocles, who has been rendered incapable of helping in physical form.

Hertz to Be a Hero is an exciting good-versus-evil battle between a brother-sister superhero team and the evil Mephisto. It is book #2 in the “Wanted: Superheroes” series. The evil Mephisto is still on the prowl, and he hopes to bring the city of Nirvana to its knees by controlling its people with a hypnotizing gas. Now that Damocles, the great superhero, is gone, who can stop this villain? Eddie Hertz, a twelve-year-old genius, and his sister, an eight-year-old super-powered girl named Samantha, have a plan—lure Mephisto into a trap by using themselves and Eddie’s superhero invention as bait.

In previous stories, our heroes, Eddie and Samantha Hertz, faced earthquakes and hypnotized zombie-like people. What could be worse? Birds. Yes, birds. And lots of them. Eagles, hawks, owls, herons, and more. The villain Mephisto has hypnotized tens of thousands of them to do his evil bidding. The situation gets even stranger. Our heroes have to battle gravity itself. Mephisto has stolen antigravity belts that allow him to fly. But the belts have a flaw, and he tries to force Eddie to perfect them. In the meantime, Mephisto uses the hypnotized birds to paralyze the city while he steals millions of dollars. Against all odds, Eddie and Samantha, their mother, their Uncle Milligan, the new Damocles, and the eccentric Dr. Gilbert G. Godwin, work together to battle the hypnotized birds and their controlling master. As usual, the entire world is in danger, and only the Hertz heroes can save it.
