He Will Be My Ruin by K.A. Tucker

K.A. Tucker's new book He Will Be My Ruin follows Maggie Sparkes and Celine, who have been best friends since Celine's mother Rosa began working as the Sparkes family nanny over twenty years ago. Though they came from completely different lives, it didn't matter when it came to their friendship. Maggie grew up wealthy and privileged and Celine was the daughter of a hardworking Latina who lived paycheck to paycheck. Yet no matter where life took them, they remained friends.

Now when Celine has been found dead, of an apparent prescription drug/alcohol suicide, in her New York apartment, it's Maggie who is responsible for tying up the loose ends of Celine's life. Finding it hard to believe that Celine would ever be capable of suicide, Maggie starts searching her apartment for clues. When she stumbles on a few diaries and a locked box with the photo of a mysterious man in it, Maggie begins to question the idea of Celine having a double life.

Did Celine really commit suicide or is there a killer out there who will do anything to silence the people that get in the way?
