Liberated from her life as a captive, Secret has hidden herself away at the sanctuary in Zion to rest and recover. Unfortunately, time is a luxury she can't afford. Before she can truly consider enjoying her newfound freedom, she must first fulfill the vow of vengeance she'd made and deal with the dark stain of her past.

As an elite assassin for the Alliance, Commander Talon Spartan is used to living in the shadows. He always figured he was meant to spend his life alone, but surprisingly, fate has other plans for him. Secret is a bright star in his dark world, and he is willing do whatever it takes to help her find the justice she seeks.

Will they be able to free her from her past, or will tragedy tear them apart before they can truly find happiness together?
