Battle Scars (Querio Series #2)

Major Athos Prescott Querio, is the pride of the Special Forces Unit. He's one of a kind. His records are all excellent, not even a single failed mission. He spent many years living in the mountain ranges, hunting terrorist and vigilante groups for the common good. He experienced the worst... days between the war without food and sleep, and losing his comrades including his best bud along the war.

Until one day, his team was given a task to locate another vigilante group who's been rumored hiding in the city to stop them from interferring with police and military operations. Back in the city after three years, he happened to meet the sister of his deceased military buddy, involving her in the investigation.
