The Adventure Girls at Happiness House

Gale Howard, Phyllis Elton, and the rest of the Adventure Girls are now freshmen at Briarhurst College. Gale and Phyllis are fortunate to be roommates at the Omega Chi Sorority in Happiness House. Briarhurst College has a new Dean, whom Gale likes very much, but many other students dislike the new Dean because they lost the privileges they had with the last Dean. Mysterious attacks are being made on the Dean, and Gale is determined to find out who the culprit is. Meanwhile, Phyllis is injured while playing hockey and later receives another injury that sets back her recovery.
