Outdoor Girls at Rainbow Lake

When Frances Earnside inherits a sleek motor boat called the Gem, she invites her Girls' Outdoor Club pals on a summer cruise down the river to Rainbow Lake, a glittering expanse of water cradled between the mountains. What begins as a leisurely adventure becomes a trial of nerve and friendship: stormy weather, mysterious strangers, and the occasional breakdown test the girls' courage and cleverness. They camp under open skies, navigate tricky currents, and learn that true adventure lies not in the destination but in the company you keep. Originally published in the 1920s, this is adventure fiction at its most wholesome and invigorating, with heroines who earn their victories through teamwork and gumption. For readers who want their excitement clean, their friendships genuine, and their horizons wide open.
