The four traveling bears have reached their Arctic destination. There they find polar bears suffering as a result of human environmental damage. Fans who have followed the series to this point will find answers to many questions while mourning the loss of a main character; there's less interest for new readers. The resolution unsurprisingly leaves room for future series developments.
