Seventeen-year-old Kim Hunter has loved strange, moody, always-in-trouble Judith since they were 14, but she's always scorned him. Suddenly, she's allowed him to take her out; but now after a week she's dropped him for older Neil, and Kim is desolate. Then Neil rings up with news that Judith has disappeared, and Kim must accompany him to London where they will seek her out among the sleazy communes, hippie pads, parks, and prostitution centers. They don't find Judith but Kim loses interest in the search after meeting Neil's 20-year-old sister Wendy, who puts them up. Kim ends up in bed, and joyously in love, with Wendy--and wins her away from her on-again, off-again, live-in boyfriend of a few years' duration. As a love story, this is pretty much on a daydream level, but it does project adolescent languishing with sympathy and identification, yet none of the self-serious self-pity so common in the genre. And the love story is intelligently filled out with Kim's everyday, walking-around thoughts and observations--and those of his father, an ordinary but likable suburbanite who is moved by Kim's evident romantic involvement to regret the passing of his own youth and to narrow the gap between himself and his son. All this gives the story texture, a shade of perspective, and a mellower tone.
