The St. Clare’s series is a nine-book run of British boarding school stories that begins with The Twins at St Clare’s in 1941. Pat and Isabel O’Sullivan arrive at their new school under protest, convinced it cannot compare to their old one, but they soon find themselves caught up in the friendships, feuds, and fun that make up life at St Clare’s.
Each book covers a new term or form, with a cast of characters that grows as the twins progress through the school. Claudine, a French girl with a talent for getting out of trouble, becomes a fan favorite when she arrives in the fourth book. The later entries introduce Kitty and follow the girls into the senior forms. The books are short, episodic, and built around the kind of school-day drama — midnight feasts, sporting matches, strict teachers — that has kept young readers coming back to them for decades.
