If you've ever come across BBC's list of 100 books, you've probably spotted A Town Like Alice by Nevil Shute. A Town Like Alice centers around Jean Paget, who was a prisoner of war during World War II in Malaya, and the man she met and fell in love with.
This book starts off incredibly slow, I would recommend really giving it a chance. It opens with a lengthy description of the will preparations for one of Jean's relatives (the book is narrated by Jean's lawyer). The beginning is very dry and technical. This is the second time that I've tried reading A Town Like Alice -- I couldn't get through it the first time. There is also some outdated language as well.
During the war, Jean and fellow women prisoners walked for thousands of miles while their captors look for a camp in which to keep them. She meets an Australian soldier, whose also a POW and risks his life to help Jean and her fellow prisoners.
An interesting read and well worth the effort.
