Wedding in the Family by Rosamond du Jardin

When Tobey Heydon got married, her fifteen-year-old sister Midge felt both joyful and sad. She was delighted that her sister was so happy and thrilled with the wedding festivities, but sad that Tobey would be leaving home. The best man, Johnny Randall, a smooth talking older man, catches Midge's eye. Later at Green Lake, Midge finds herself attracted to a good-looking, popular young man. Will she fall for this one or will her friend Tom Brooks help her to see the light?
