Chosen for Death - Tapa dura

A dynamic businesswoman, Thea Kozak is a young widow who has thrown herself into a career to overcome grief at her husband's sudden, senseless death. It's a lonely life, but slowly Thea is coming to terms with her loss and starting to rebuild her world. When Thea's younger sister Carrie is brutally murdered, Thea must once again come to grips with loss... and with a deadly puzzle.
Carrie was always the baby of the family: a beautiful, blond waif living among dark giants. An adopted child, Carrie was surrounded by a loving family - but never felt truly at home. Her dearest friend was big sister Thea, who was always there to "fix things" whenever Carrie's life fell apart. But Thea's love couldn't ease Carrie's loneliness. In her twenties, Carrie became convinced that only by finding her birth parents would she find true peace. Her search for answers brought only death...and Carrie's murder has left Thea with more questions than answers.
The police have no leads and everyone - especially Thea's family - seems willing to accept the murder as one of life's tragedies. But Thea can't let Carrie go unavenged. As she retraces her sister's last months, Thea confronts ugly facts that suggest she didn't know Carrie as well as she thought.
