Marta convalesces as a mysterious illness sweeps through Olympus Town and Lukrum Colony. When IMSF realizes one of its own has died as a result, it races to determine the cause, origin and mode of transmission before time runs out—and more lives are claimed. Back in present day, Vladimir Chuprov, a Greenpeace activist, sheds light on an indigenous health crisis being kept quiet by the Russian state to benefit their Arctic oil endeavors.
