Infinite Number of Parallel Universes [EPUB ebook] 

Four friends from wildly different backgrounds have bonded over Dungeons & Dragons since the sixth grade. Now they're facing senior year and a major shift in their own universes. Math whiz Archie is struggling with his parents' divorce after his dad comes out as gay. Mari is terrified of her adoptive mother's life-altering news. Dante is carrying around a huge secret that is proving impossible to keep hidden. And when Sam gets dumped by the love of his life, everyone is ready to join him on a cross-country quest to win her back. The four quickly discover that the road is not forgiving, and that real life is no game. They must face a test of friendship where the stakes are more than just a roll of the dice–they are life and death.
