China Sky, first published in 1941, is a romance by Pearl S. Buck set in war-time China. Dr. Gray Thompson, an American missionary doctor, works alongside Dr. Sara Durand in a hospital he has built in a small Chinese village, as Japanese forces approach. When Gray returns from a visit to America a trip, he shocks Sara (who is in love with him) by introducing his new socialite wife, Louise. In the midst of bombing attacks on the village, Dr. Thompson continues to help the local residents, and especially the insurgent leader Chen-Ta. To protect the hospital, a high-ranking Japanese prisoner gets a message to the Japanese commander which stops the bombing but, eventually, Japanese paratroopers land in the village, and fierce fighting ensues. China Sky was also the subject of a 1945 movie of the same name.

Pearl S. Buck (1892-1973) received the Nobel Prize in Literature in 1938 and was the author of numerous novels, short-stories and works of non-fiction.
