Fergus lives down in the deepest, darkest sea and is scared of just one thing the light! From award-winning creator Anna McGregor (author of Anemone is Not the Enemy) comes this hilarious tale of the deepest of sea creatures. Seamlessly combining humor, narrative, and nonfiction, McGregor introduces young readers to the wonders of the oceans midnight zone, where no sunlight at all is able to penetrate. We meet Fergus as he hides from a parade of sea creatures that use bioluminescence to find their way in the dark. At least, we think he is hiding or is it something else entirely?
