A summer at Indian Pond, Maine, in a cabin deserted by her Uncle Bill takes beautiful and popular Charlene Fairhill out of her wealthy environment into the natural course of rustic life. Old faithful Peter comes up to spend the summer and with Eric and Dawn, the four spend many wonderful days pursuing the summer activities the region offers. As the other three talk in earnest about their interests, Charlene has a vague feeling of being left out, for her only interest lies in landing Eric, her best friend's beau. A third admirer comes on the scene -- Dan Harris -- a popular singer who had promised Charlene an autumn audition with Bud Mallory's band. Her dream comes true when, at a summer dance, she and Dan perform and Mallory accepts her for a singing engagement. That same dream is shattered when Charlene discovers that in an effort to win her affection, Dan paid the bandleader for his benevolence. This news plus the realization that Eric can never be hers sends Charlene wildly across the river to spend a grievous if enlightening solitary night pondering her own conceit and egoism. The amethyst she finds cannot compare with the real treasure in her heart -- the knowledge of her own mistakes and the clarity of her path to improvement. The insatiable Charlenes of the world can profit well from this girl's painful realization. Sensitively told, realistically enacted.
