This delightful book tells about a group of smart youths who get up to some wonderful adventures together – and save one another from troubles. The unofficial leader of the group is Grace Harlowe, the title character. When Anne Pierson comes to the class at the beginning of the year, they decide to take her under their wing. Anne has a lot of troubles at home, but will true friends make her happy?

The four series follow Grace Harlowe and her friends through high school, college, abroad during World War I, and on adventures around America. In The High School Girls Series, Grace attends Oakdale High School with friends Anne Pierson, Nora O'Malley, and Jessica Bright. The four promote fair play and virtue while winning over troubled girls like Miriam Nesbit and Eleanor Savell, playing basketball, and founding sorority Phi Sigma Tau. The group becomes friends with boys in their acquaintance: David Nesbit, Tom Gray, Hippy Wingate, and Reddy Brooks, forming "The Eight Originals."

The College Girls Series sees the friends part ways: Grace, Anne, and Miriam depart for Overton College, while Jessica and Nora attend a conservatory. The Eight Originals gather on holidays, but the seven College books focus on the three at Overton, along with new friends like J. Elfreda Briggs. They form Semper Fidelis, a society devoted to aiding less fortunate students at Overton. Following graduation, Grace rebuffs offers of marriage for "what she had firmly believed to be her destined work," managing Harlowe House at Overton.
