At All Costs [EPUB ebook] 

Kyle and Mike share a dream of playing college football. They’re both members of the Central High Trojans. And lately their dream is in danger, because Mike has taken some serious hits. A head injury is affecting his performance on the field-and it might mean he’ll have serious health problems. When Kyle figures out a way to cheat the football program’s new concussion tests, he decides he’s protecting Mike’s chances of playing college ball. But is he also putting Mike at risk of further harm? And when Mike’s symptoms get worse, will Kyle pressure his friend to leave the game or pressure him to play?
