ICE BEARS AT ICE EDGE

Stranded on a broken-off ice floe, a polar bear plunges to the rescue when her cub slips off the edge into the sea.

With cold almost tangibly radiating from expanses of ice and dim, hazy skies, even the frisky cub, rolling and tumbling in the feathery March snow, brings barely a hint of warmth to Minor’s frozen Arctic seascapes. Meanwhile his mother stands at the edge of the ice and searches the choppy waters for an unwary seal—until with a “CRACK!” both bears suddenly find themselves floating away from safety on a fragment of ice so small that the cub loses his footing. Before he can drown, his mother dives in after and, bearing him on her back, paddles back to shore, where the two nuzzle affectionately and then wearily pad off toward their unseen den. The disquisitions on climate change and on polar bear behavior, diet, and life cycles that Burleigh tacks on afterward are well meant but seem likewise laborious; younger audiences are likely to respond more to the displays of elemental connection between parent and offspring that infuse the episode and its illustrations.

Tender, if a bit unwieldy from being so heavily back-loaded with background facts.
