Billie Campbell was just the type of a straight forward, athletic girl to be successful as a practical Motor Maid. She took her car, as she did her class-mates, to her heart, and many a grand good time did they have all together. The road over which she ran her red machine had many an unexpected turning, -now it led her into peculiar danger; now into contact with strange travelers; and again into experiences by fire and water. But best of all, "The Comet" never failed it's brave girl. "A series of clean, wholesome books of adventure which will appeal to the girl who loves outdoor life. These charming books fill a long-felt want -- they are healthy books for healthy girls."
