"When I walk, every once in a while someone notices they can't hear my footsteps. Do you know why? Dr. E. Paul Zehr knows. I'm training to become Batman. Most of the population wouldn't understand this... but beneath and entwined in the soul of many men is a hero-in-the-making. Training for that moment that will, thankfully, never come. The moment when he must be a hero. The moment he trained for. They'll never hear me coming. In this book Dr. Zehr knows exactly what our giddy souls are doing. Here he tells our secret."
