This is Kallik. Kallik is a polar bear cub. She has a brother named Taqqiq and a mom named Nisa.
The ice on which Kallik and her family live is melting away. So they have to go to the place where the ice never melts.
Since the ice is melting away, they have to swim some parts of the way to get to the place where the ice never melts. It is very difficult for Kallik to do this because she is a cub.
While Kallik and her mom were swimming to the next piece of ice, an orca pod came up under them. Nisa made sure that Kallik made it to the ice. After Kallik was on the ice, the orcas ate Nisa. This scared Kallik.
Kallik remembered the stories her mother told her of the place where the ice never melts. So she decided to go there so she could survive. She also was very worried about her brother. She wondered where he was.
While Kallik was on her way to the place where the ice never melts, she came across, Nanuk, a female polar bear. Nanuk took care of Kallik for a few days. The flat-faces (humans) found the bears at the gathering place and put them on a plane so they could take them to the place where the ice never melts. During the flight, the plane was acting strange and it crashed, killing Nanuk.
