Mark Of The Two-Edged Sword

A car accident killed Caleb Promise's parents. Mysterious? Normally not, but when your father was the master strategist for an undercover military strike team and sole survivor of a mission-gone-bad, his death is very suspicious.
Years later, the old stone monestery orphanage behind him, Caleb is lost in bitterness and drink, or is he? What happened in that orphanage changed his life.
Can he overcome his personal issues to figure out the clues his father left him? Clues encrypted in their relationship. If he can, with his father's help, he will cut through layers of deception to the core like a two-edged sword. If he succeeds, they will leave their mark... the Mark of the Two-Edged Sword.
