Two doctors race to save the world from a deadly disease. Epidemic researcher Dr Avery Thatcher is not prepared her for what she finds at a remote Antarctic base: the one man she never wanted to see again and a mysterious illness ravaging inhabitants. Avery will do whatever it takes to discover the disease's cause, and she vows to keep her heart-breaking history with Grant Jones in the past-even if their passion threatens to reignite. For Grant, ending this outbreak and regaining Avery's trust are vital. As their hunt to contain a lethal bioweapon escalates, he'll put everything on the line to avert disaster. But will another insidious threat stop them both cold?
