This story tells about the aftermath of the events in Frozen. After Elsa finally learnt the key to control her power, she continues living her life as a Queen, now with the castle's gates open at all times, with Anna, Kristoff, Olaf and Sven. Days go by, she watches Anna and Kristoff leading a normal life, she goes out to the market, and she watches her people smiling and crying. And then one day, Grand Pabbie tells her that her ice powers will not last forever, and it's her choice whether to keep her ice powers, or to lose them...

When Elsa brought summer back to Arendelle, all was great and peaceful. But when the arrival of their cousin's family (Rapunzel, Eugene Fitzhurbert, and their new daughter Lily) triggers a freak accident that sends both Elsa and Anna through a portal to the modern world, how will the two survive? And will they return to Arendelle before the heavily pregnant Anna gives birth?
