Human Rites by Amelie Nothomb
"Another winter of war and survival demands sacrifices...Food is in short supply and the cold is unbearable. In a tantalising menage-a-trois between a Professor, his assistant, and a student, only the books bear witness to their plight. Human Rites is a provocative play that questions our natural instincts and asks how far we are prepared to go in order to survive. "
