Malice

"The perfect life becomes the perfect nightmare in a twisting novel of psychological suspense from #1 USA Today bestselling author Jennifer Jaynes ... Dr. Daniel Winters is living a fairy-tale life. He has a beachfront home in Malibu, a career as a respected pediatrician at a thriving Los Angeles practice, and a gorgeous new wife, Mia. For a man whose past was rife with mental illness, addiction, and thoughts of suicide, it seems too good to be true. Then Daniel learns that a fellow pediatrician and his family were found slaughtered in their home. It's just the first chip in the facade of Daniel's perfect life. Little by little, everything starts to fall away. At work, his career becomes at risk when he's asked to remain silent about a dangerous new drug. At home, Mia has gone from an affectionate newlywed to a mysterious woman carefully hiding secrets--and possibly a lover. Then, another doctor is found dead, and as Mia's behavior becomes increasingly suspicious, Daniel begins to wonder: Is paranoia getting the best of him ... or has his fairy-tale life become a nightmare worse than he could have ever imagined?"-- (Source of summary not specified)
