Andromeda's Choice (Legion of the Damned Book 2)

Andromeda McKee rebuilt her life in the violent embrace of the Legion of the Damned in the days when cyborgs were first being introduced. Now she must choose between her conscience and her desire for vengeance...
 
In a different world, Lady Catherine “Cat” Carletto would never have left her pampered life behind. But when Princess Ophelia became Empress Ophelia in a coup that claimed the lives of the princess’s brother and all who supported him, including the Carletto family, Cat had to hide—or die.
 
She became Legionnaire Andromeda McKee, and now she’s a battle-scarred veteran who knows how to kill.
 
Summoned to Earth to receive the Imperial Order of Merit from the empress herself, Andromeda learns that she isn’t the sole surviving Carletto—her uncle Rex is not only still alive but also the leader of a resistance group determined to overthrow Ophelia.
 
Caught up in a web of intrigue, Andromeda realizes that the moment is coming when her revenge will be at hand. But will she be able to act, or will she be betrayed by those she has come to trust?
