"Middle-aged businessman Hiroshi Nakahara has been catapulted back into his life as a 14 year-old but with all his adult memories and knowledge intact. As he settles into his past in a way that only someone who has seen the future can, he experiences again the friendship, the exhileration and the love of youth. But sublte changes occur in his history and, as the summer break reaches its conclusion, he starts to ask himself 'What can I do to stop my father leaving?'" -- p. [4] of cover.
