Twenty years ago, Alexa Rodriguez's sister disappeared without a trace. The trauma drove Alexa to become a private investigator. No matter how many cases she solves, there will always be a hole from the one that haunts her.

When Dean Campbell hires the HEARTS Agency, he has no idea what has happened to his sister. The police aren't taking her disappearance seriously, but Dean knows Mandy--and he will do anything to bring her home safely.

As the line between investigator and client blur, the hunt for Mandy continues. But will their need for one another compromise their search?
