Every game is a universe!

Parker still doesn't know why she has a phone that can call other universes. But her life seems to have settled down. She just leaves the phone in her drawer and forgets about it. Then her best friend, Wally, starts acting weird. And Parker starts to think maybe he's not Wally at all. It's almost like he's been replaced... by a character from a video game.

Parker doesn't understand video games. But she'll need to figure them out. Because soon she's off on an adventure across time and space where every video game is its own universe, and where the only thing that can bring Wally home is true friendship.
