There are many reasons to be thankful for the life and work of author Betty MacDonald. If you have a love/hate relationship with chickens, her best-seller “The Egg and I” will satisfy both passions. If you have children in your life, her “Mrs. Piggle Wiggle” series will likely delight and challenge them. And if you suffer from self-doubt her book about finding work in the Great Depression, “Anybody Can Do Anything,” may help.
