Mary Louise and the Liberty Girls

Step into the enchanting world of The Bluebird Books, a beloved series that captivated teenage girls in the 1910s and 1920s. Originally conceived by the renowned L. Frank Baum under his Edith Van Dyne pseudonym, this series features the adventurous escapades of adolescent girl detectives. Baum penned the first four novels, possibly with assistance from his son, Harry Neal Baum, on the third. The series kicks off with Mary Louise, a heartfelt tribute to Baums cherished sister, Mary Louise Baum Brewster. After an initial rejection from his publisher, who deemed the heroine too headstrong, Baum crafted a new version, though the original manuscript remains lost. In this exciting fourth installment, Mary Louise Burrows and her friends unite to support soldiers during World War I, as she enlists Josie OGorman to thwart a treasonous plot against the government.
