Frozen Solid, James Tabor

This book has gripping descriptions of the South Pole research stations, and the claustrophobic setting adds ambience to an already chilling (excuse the pun!) bio-terror thriller.
Top virologist/epidemiologist/extreme diver Hallie Leland is sent to the ASRS- the Amundson-Scott Research Station- known to the scientists there as ARSE, to replace a dead colleage and friend. When Hallie arrives, she finds that the station is home to more than neurotic researchers and dedicated scientists- it is also hosting a deadly disease.
Hallie must find out what is going on, in time to save the station- and the world, but this clever thriller offers some thorught-provoking questions about what "saving the world" might mean.
A solid entry into the world of icy thrillers, along the lines of The Trudeau Vector (a North Pole thriller!)
