  • You need standalone books without series commitments.
  • You're looking for high-octane action rather than psychological tension and investigation.

About this book

Laura Foster appears to have everything she wants. At twenty-seven, she married widower Peter Foster, moved into his Silicon Valley home, and helped raise his two children. Twelve years later, her career is thriving, the children have left home, and Peter's company is approaching FDA approval that could result in significant stock gains. Then a series of accidents that seem too deliberate to be coincidence suggest someone is trying to kill her. Laura has no known enemies, but she begins to suspect her husband is hiding secrets. As she investigates the family's past, disturbing details emerge. She becomes increasingly concerned about what really happened to Peter's first wife and why someone would want to harm her. The Stepfamily explores family secrets, dangerous marriages, hidden pasts, and Silicon Valley intrigue as Laura races to uncover the truth before it's too late.
