Mount Desert Island residents Richard Johnson and Ruth Gortner Grierson have produced a children's alphabet book that focuses on the wonders of Mount Desert Island and Acadia National Park. The hardcover book, A is for Acadia, features vibrant color photographs by Johnson that highlight the island's natural beauty. It includes, among others, images of harbor seals and barred owls as well as landscapes such as Sand Beach and Bass Harbor. Grierson's text accompanies each image. Overall, the book is slightly more sophisticated than many ABC books with roughly 140 words per image. While it is aimed at young children, it is fun and informative and should appeal to residents and visitors of any age. The letter topics range from Acadia, to lighthouse, to nuthatch, to zoophtye.
