Partner — Lia Silver

Echo has devoted her life to protecting her sister. In all her years as a genetically engineered assassin, Echo never met anyone like DJ Torres before. The captured werewolf Marine offered her trust, friendship, love, and the hope of freedom -- not only for herself, but for the frail clone-sister she won't leave behind. But will Echo's dark secret destroy their hopes for the future? DJ Torres would give his life to save his buddy. DJ has spent his life accomplishing the impossible. But now he's faced with a dilemma that threatens to crush even his bright spirit. DJ can't rescue his captured buddy without fleeing the lab. Echo can't flee the lab without abandoning her hostage sister. Will DJ be forced to choose between his best friend and the woman he loves? Will love keep them together or tear them apart? Still held captive by Wildfire, a shady government agency, DJ and Echo are forced to go on a series of missions, from undercover escapades at an excruciatingly elegant diplomatic party to a desperate battle in a terrorist compound. Their relationship grows stronger under fire… until they are confronted with a terrible choice.
