Kate Beaton gained an international following for “Hark, a Vagrant,” a quirky, satirical, historically informed comic strip. Beaton’s newest book takes a very different turn. It is a deeply personal graphic memoir called “Ducks: Two Years in the Oil Sands" about the time she spent working in the oil industry in Alberta, Canada in the mid-2000s. The book is a brutally honest exploration of class, migration, misogyny, and the culture of her homeland: the island of Cape Breton, in the Atlantic province of Nova Scotia. We listen back to a conversation with Beaton at the 2022 Portland Book Festival.
