A group of scientists in the Antarctic face a desperate battle for survival against a deadly, mysterious enemy in this “engrossing thriller” (Publishers Weekly). Having spent the summer conducting fieldwork on Livingston Island off the coast of Antarctica, marine biologist Andrew Berrister is looking forward to getting back to civilization. But his final days in the forbidding climate take an unexpected turn when Berrister and his colleagues discover that they are not alone on the island . . .   Suspecting that the intruders are a crew of illegal whalers, the scientists know they have to get out fast. But departure becomes nearly impossible when their supplies are sabotaged and two members of their shore party disappear.   As Berrister and his remaining companions flee across the treacherous, icy terrain, they are relentlessly pursued by ruthless killers whose true reasons for being in Antarctica are darker and more dangerous than the any of them could have imagined . . .   “A breathtaking tale of intrigue and fortitude reminiscent of the vintage adventure tales of Alistair MacLean.” —Kirkus Reviews   “Beaufort carefully crafts the personality of each team member, while the action-packed plot builds to a shocking crescendo.” —Publishers Weekly
