The Best Mystery Novels About Dark Family Secrets

Woman Last Seen by Adele Parks, from MIRA books.

Step-mom Leigh Fletcher goes to work one day but then doesn’t come home. The family is left shattered with her disappearance. Kai Janssen leaves her glamorous penthouse one day and seemingly evaporates into thin air. Her wealthy husband is distraught. Detective Clements believes the disappearances of these women might be connected. But how far will she go to discover the shocking and devastating truth…

Families, whether biological or found, can be great. They are a place to go to during holiday breaks, your birthdays, and a place to rest when life gets you down. Or at least you like to think so. But, what if with familial sanctuary comes a cost? What if the comfort of family and home comes with a dark obligation, an obligation to keep at all costs?

Family secrets are something we never really tire of reading about. There are so many tiny moments that mean something entirely different to every family that they decide to sweep under the carpet. But these secrets fester under that rug, becoming more than just dust mite entities. They become anchors that, instead of grounding the members of the family, hold them tight, keeping them close to the ground where the bodies may lie.

That is what the stories below deal with. What it means when a place and people you called your home turn out to be something completely different, and you realize you are no different. The books for this list range from a little bit dark to incredibly dark. But, all deal with what happens when you start to peel layers away from a group of people with shared lives and stories.
