“The huge humpback whale dips and dives. Her sleek black sides shimmering, she spyhops, lobtails, flashes her flukes.” The whale becomes entangled in nets used for crab fishing. She struggles, tiring, before a team of divers arrives and embarks on a rescue mission. Will they free the whale in time to save her? Robert Burleigh’s tense, dramatic picture book narrative is based on an actual event that happened off the California coast in 2005. When the whale is finally freed, she swims past her rescuers and gently nudges each one, “as if saying thanks.” Wendell Minor’s gorgeous illustrations offer a variety of arresting perspectives of the whale and the divers in the sea in an account that concludes with additional information about the event on which it is based, as well as more about whales and whale rescues.
