After the longest winter of her life, Vivian is thrilled to have Ginny back at her side. But joy soon turns to shock when the group learns that not only is Hope Springs in contact with other survivors, but that the CDC is working on a vaccine. And Angus could be the last hope for the human race.



With an armed escort, the group sets out on a mission to get Angus to Atlanta. But the world proves to be more dangerous than the people of Hope Springs believed, and their lack of preparation ends in deadly results. Vivian knows they must get Angus to Atlanta if they want to save the human race, but it doesn't take long to discover that this might be the most dangerous journey they have ever made. With trouble around every corner and their losses piling up, the stakes are higher than ever before.
