I think that the book Neversink is a really good book for kids 9 and up. It is about a puffin named Lockley J. Puffin. He lives in an ancient world civilized by animals. His home Neversink was an independent colony home to auks and puffins. Then a new ruler of the owls comes into play and conquers Neversink. He is forcing the birds to pay tribute in fish that are cooked into a special food. Lockley becomes angered because his wife, Lucy, is the only one who can make the food, so she has to cook day and night. Lockley sets out on an adventure to try to help his wife, and save the rest of the colony.
