Publisher's Synopsis
Harold is an iceberg - lettuce. (But he doesn't realize the 'lettuce' part because some of his sticker has been ripped off). So one day when he sees a documentary about how the icebergs are melting, Harold starts to worry, thinking that he's melting too. As his anxiety grows and grows, and he tries to find a way to stop melting, his fellow food friends try to help him cool down in a different way.
