Four fun retro "Peggy" books by Dorothy Martin. Fun retro young adult series published in the 60s and 70s by the Moody Youth Library, later changed to Moody Teen Books in the 70s when "Teen" became the fashionable name for young adults. These are also under the banner of "The Moody Bible Institute of Chicago".
