Border Marker Watcher

Lin Zheng, commander of the "Blade" squad, bears the codename "Thorn." Her battlefield lies on smoke-filled borders and behind enemy lines, where danger lurks at every turn. There is no room for romance, only a blood-and-iron mission and comrades who entrust one another with their lives: the rock-solid veteran squad leader Shi Lei, the electronic ghost Chen Mo, the angelic sniper Ye Xiao, and the charging spearhead Zhang Meng. When a new kind of terrorist threat shatters the peace, Lin Zheng will lead her squad into the depths of danger, using their own flesh and blood to build the final boundary marker. Loyalty is faith; protection is life. The boundary marker will stand as witness: they are guardians who will never retreat.
