Full disclosure: #NealShusterman is one of my favorite authors of all time, so I have been looking forward to #GameChanger, and it did NOT disappoint. The book follows Ash, a high school football player who--every time he gets hit--finds himself transported into other universe or timeline where there is always something different from the one before. As this is an advanced release, I will not give away any spoilers. However, like all Shusterman novels, and what makes him so great, is that he takes a thread of modern truth or social criticism and sees it through to a logical conclusion. "OK, if this is true, then what if..." This book covers topics such as racism, socioeconomic bias, white privilege, gender issues, sexuality, abuse, morality, and more--all while asking the reader to also investigate their beliefs on each topic. This is not one to miss. Many thanks to the publishers and #NetGalley for the advanced copy.
