Mason and Ty were once the very best of friends...Until 7th grade, when Ava Petrakis came along. Mason can trace everything bad in his life to that terrible fight they had over the new girl. The one thing he’d give anything for is a do-over. But that can’t happen in real life - can it? As a science kid, Mason knows do-overs are impossible – so he can’t believe it when he wakes up from a freak accident and finds himself magically transported back in time. His parents aren’t yet divorced and his beloved sheep dog is still alive. Best of all, he and Ty haven’t had their falling out yet. It makes no scientific sense, but Mason is determined to use this second chance to not only save his friendship, but to do other things differently—like trying out for the football team and giving new friends a chance. But despite his best efforts, will he be able to stop the chain of events that made his previous life implode?
