Emma Ketchum, daughter of Ash and Misty Ketchum, is traveling with her fellow Pokemon Trainer friends through Johto when they get mixed up with an evil organization that is, yet again, attempting to take over the region. Plans, backup plans, and backup backup plans backfire, resulting in a pretty chaotic, disastrous situation: time travel. Not only does Emma have to worry about safely getting back to the future with her friends, but on making sure her newest friends don't find out who she really is. Can she get back to where she truly belongs, or will she forever be stuck in the past?

A re-writing of Mystery Dungeon, this story is about a timid Riolu who meets a badly-wounded Eevee and a shy Chikorita who give him the courage to confront his fears... And find secrets that could change the Pokemon world Forever.
