Watch Me Disappear by Janelle Brown

When she goes hiking and never comes home, her husband can't understand it.  There's no body, just a broken cellphone and a hiking shoe to be found.  They have to wait a year to get a death certificate.  As he waits, he learns that as much as he loved his wife, he didn't know her...

Spiegel & Grau and Edelweiss gave me the opportunity to read this book for review (thank you).  It will be published July 11th.

His daughter starts having visions of her mother.  He can't believe it because that would mean she left him on purpose.  But it makes him start looking into past and what he finds astonishes him.  She was another person in her past.  Maybe she's making herself into another person in the present.

It seems she was fearless as she grew up and she hung out with anyone she wanted to.  She would betray those that loved her, steal money to live on, and keep moving.  As you trace her past you find out devastating secrets.  There's one that was hidden too long and should have been recognized long ago.  The ending is interesting and ironic.  Everyone is going on with their lives but they've all changed...
