Hero's Revenge — Dee J. Stone

Fifteen-year-old superhero X-Ray wants only one thing: revenge. Consumed with guilt for his best friend's murder, he hunts for the ShadowBlades, the villains responsible. The problem? They're in hiding. When he stumbles upon a group of villains seeking recruitment into the ShadowBlades, he comes up with the perfect plan -- to send one of their own undercover to join this group and ultimately the Blades. Stealth, the newest teen member of the League, volunteers, but X doesn't know if he can trust her. After seeing how powerful she is, he realizes she's his only shot at taking them down. Stealth stirs feelings in him he's never felt before and X can't bear the thought of losing someone else he cares about. But she's too deeply involved in the plan. Pulling her out may put her life even more at risk and X has never been this close to having his revenge…
