What to read after For I Could Lift My Finger and Black Out the Sun?

My name is John Black. I used to be your typical nerd, a total weakling, letting bullies like Bobby Graden push me around. Then one day, Bobby and I got hit by a car. Somehow, the accident changed us, as if something inside us responded. It made us strong. More than strong, actually. It gave us power. That power brought us together, our shared secret creating a friendship despite our differences. Bobby and I could do things no one else could, and it was exhilarating, fun. Until the day we found out we weren't alone. And that, for others, power can be deadly serious.
