About this book

Grace is skilled in combat and survival, equipped with weapons and a plan. After a terror attack causes societal collapse, she escapes her college town with a single objective: reunite with her family, regardless of the cost. Tom is a disabled veteran who operates a tracked wheelchair fitted with gun mounts. He has endured significant hardship and pain. Grace and Tom join forces to traverse a hostile, dystopian landscape in search of Grace's family. This sequel to Locker Nine follows the pair through a violent post-apocalyptic setting populated with vivid, memorable characters.
