Chambers, Sally: Out of the Shadows

This was a deadly game and she didn't want to play. Three months ago, Ali Lamarque's mother died in an accident Ali is convinced she could have prevented, and what little faith she had is fading. Grief-stricken, her father, a renowned scientist, has sold their California ranch and buried himself in his work. He will soon leave for Brazil's Amazon Rainforest on business. Ali's relationship with her childhood best friend, Kane, is changing, and suddenly she's being followed. Insidious and relentless, it's harassment with no proof it ever happened. With her life in turmoil, and against her father's wishes, Ali takes a break from college to go with him, hoping the trip will help heal their grief and her guilt. It will give her time to sort out her feelings for Kane-and leaving would stop the stalking. But Ali didn't anticipate the dangers that would confront her or know that her choices would make the difference between living and dying for not only herself, but countless others.
