Tireless traveler and loyal friend Captain Dog and the crew of the Pearl embark on an important mission into the bowels of the Earth. Joining navigator Snake, cook Duck, and boatswain Pig, we'll see how glaciers flow and volcanoes weep, how diamonds are born and black smokers breathe, how fragile cave decorations are and the amazing inhabitants of the Great Coral Reef. This book is the debut of artist, writer, and geologist Maria Nesterenko, a participant in the illustrator's exhibition at the Bologna Children's Book Fair and a finalist in the ABCDbooks competition. Her witty and vibrant illustrations, charming characters, and child-friendly explanations reveal a fantastically beautiful world of our planet's underground and underwater treasures.
