The Gift Of Rain By Twan Eng Tan

Penang, 1939. 16-year-old Philip Hutton is a loner. Half English, half Chinese and feeling neither, he discovers a sense of belonging in an unexpected friendship with Hayato Endo, a Japanese diplomat. Philip shows his new friend around his adored island of Penang, and in return Endo trains him in the art and discipline of aikido. But such knowledge comes at a terrible price. The enigmatic Endo is bound by disciplines of his own and when the Japanese invade Malaya, threatening to destroy Philip’s family and everything he loves, he realises that his trusted sensei to whom he owes absolute loyalty has been harbouring a devastating secret. Philip must risk everything in an attempt to save those he has placed in mortal danger and discover who and what he really is.
