Sunny is just that-sunny. Always ready with a goofy smile and something nice to say, Sunny is the chillest dude on the Defenders team. But Sunny's life hasn't always been sun beamy-bright. You see, Sunny is a murderer. Or at least he thinks of himself that way. His mother died giving birth to him, and based on how Sunny's dad treats him-ignoring him, making Sunny call him Darryl, never Dad -it's no wonder Sunny thinks he's to blame. It seems the only thing Sunny can do right in his dad's eyes is win first place ribbons running the mile, just like his mom did. But Sunny doesn't like running, never has. So he stops. Right in the middle of a race. READ THE RUN SERIES: Ghost. Lu. Patina. Sunny. Four kids from wildly different backgrounds with personalities that are explosive when they clash. But they are also four kids chosen for an elite middle school running team-a team that could qualify them for the Junior Olympics if they can get their acts together. They all have a lot to lose and a lot to prove. Not only to each other, but to themselves.
