Bestselling author Audrey Wood and artist son Bruce create an undersea counting book that's full of the same vivid imagery and fun story elements that have made their alphabet books so successful!

It's an undersea countdown in the newest book by bestselling author Audrey Wood and her dynamic, digital-artist son, Bruce. Follow ten little fish as they swim along a beautiful ocean reef, one by one departing from the school for different reasons, eventually leaving one fellow all alone. What will he do? Along comes another, and that makes two! Soon he becomes a father and she becomes a mother--with ten little children of their own. The rhyming text helps readers go from one to ten and back again, and each illustration pops with all the color and depth of an underwater playground.
