‘I read The Squid, the Vibrio and the Moon to my grandson and he was absolutely riveted. As soon as I finished, he demanded that I read it again. He was swept up by the story, the incredible characters in it and wonders of the relationships that have evolved.’ — David Suzuki, Scientist, Environmentalist and Broadcaster
