Watch Me Disappear by Janelle Brown

Billie, Jonathan and Olive are the perfect family except when Billie goes off on a hiking trip and doesn't come back. No body is found, no note, no clue how or why she disappeared - only a husband and daughter who don't understand and can't move forward. Jonathan is in the process of writing a memoir about his love affair with his wife only he begins to find odd things that may suggest his wife had a secret life. Olive begins to get visions of her mom and won't believe that they may be connected to a head injury. Instead, feeling that her mom is still alive and wants to be found, Olive tries to keep her family from unraveling and her dad from filling Billie's place with another. When do the lies and secrets become too much to bear or the made up life to hard to live? Plays with your emotions and like "Gone Girl" you find yourself questioning who are the good guys and who are the bad guys.
