What a read! The author writes about murder and research in the Antarctic environment from the study of ice cores to observation and studying penguins. The detail is entrancing and the murder difficult to solve. Valena Walker is a young masters degree graduate student who finds herself in this hostile environment where she is to pursue glacial studies with her professor. However, her professor has been detained and then arrested for the murder of a journalist who died on a trip at a research site supervised by the professor. Her lifelong goal has been to visit this remote continent with its potential for study and research but she is unsure whether or not she will be able to complete her work for her degree. Determined to clear her adviser, she interviews individual after individual about what happened. In this closed society everyone seems to know everyone's business. Eventually, of course, she alerts the murderer to her efforts and almost becomes a victim herself. Good, good read.
