And then a young woman, Parsley, comes out of nowhere into Sara's life. Found in their garden, they have no idea where she is from.

Sara and Parsley begin to fall in love, but disaster strikes when Sara’s brother Noah is taken by the creatures. They set out to find him, across a landscape of merciless terror, haunted by death. But can Parsley truly be trusted in a world where humanity is as scarse as humans themselves?
