Double

The story of Double presents Tracy as an intelligent and spirited young woman who thought she was trapped by the bad choices of her past. When out in the world she demonstrates warmth, courage and caring that she had never been given a chance to show before.
Tracy, in prison for killing her abusive husband, thought she'd never get out. So much of her life wasted. But unexpectedly, she is given a chance-a remote chance-to get out when a police task force proposes that in exchange for a possible pardon by the governor she impersonate her double, her identical twin sister Carolyn who she had never even met. Carolyn had been murdered in Mexico because of her involvement with a drug ring. The two sisters had been separated at birth; Carolyn adopted by a socially prominent couple.
There would be danger, but Tracy decides to take a chance. What the hell-what did she have to lose, except maybe her life? Tracy's odyssey as Carolyn is full of unexpected twists and turns; friendship, love, compassion, betrayal.
