Twenty-year-old Zoe Kate is young and naïve, and quite frankly a loner. When her lifelong friend, Adam Boggs, comes home for the summer they find themselves thrust into the middle of a zombie plague. As they flee their hometown in hopes of finding safety, they come across two other survivors, Emilie and Gus. The group of four quickly form bonds and must make difficult choices at every turn in order to stay alive. They will witness unimaginable horrors and experience unthinkable losses as life and death mix together in ways that were never meant to be. Things aren't always as they seem when God's Grace has been Lost to humanity.
