This book is about "how someone can claw the truth out of the mud, piece by piece, within a system where evidence can be delayed, questioned, and dismissed." It isn't the cheap promise that "justice will always triumph over evil." Instead, it shows that "every court victory comes at a tangible cost": time, health, relationships, and the trust of someone you don't want to let down. Zhang Haochen has two things in his hands: the law, and a skateboard. The former lets him speak in court. The latter lets him cross an alley before the road is closed, climb into a factory before security locks the gates, and reach a witness before they change their mind. He needs both. This book doesn't intend to portray the justice system as either a black box or a sacred temple. It's a machine that sometimes jams and sometimes favors the wealthy, but there are people working hard in every part of it.
