Emmi Moon is your average high school girl. On the day that she is incredibly late she gets a gift from her grandmother, a necklace that has been passed on from generation to generation. A shiny blue crystal necklace. Not knowing that in taking the necklace she would be sent into another world. Except she wasn't the only one. There are five others each with a different colored crystal, all trying to get home. And to get there they need to obtain a certain key. A key to unlock something they didn't think was possible. Portals.
