Battle for Gray Tower

After the world is shattered by two life-changing events, civilization is divided into two major factions. When a charismatic leader organizes an attack on Gray Tower with promises that everything the Darklings desire is within those walls, four young people must journey into the dangerous world of their enemy. To reach an underground contact who will lead them to ammunition and supplies, these four friends will defend themselves against ambushes and betrayals and learn that trust goes deeper than skin. They will be forced to put their faith in the very creatures they had been taught to distrust. It will take the strength of all four and the help of strangers to save each other and Gray Tower.
