From B&N:
Jessie and her brother, Sean, lived in Chicago-until their father became a bush pilot on the Alaskan frontier. Then their father's plane hit a killer storm and vanished in the icy mountains. Everyone knew there was no hope-except Sean and Jessie. Alone, they set out on an impossible mission to rescue their father...and with the help of an orphan polar bear cub challenged the wildest peaks on earth.

A good adventure with two kids and a bear. Some close calls with bad guys and dangerous situations. Some good luck and guts and a good ending. If Alaska calls to you reading this might make you want to be here even more.
