The Conjoined: A Novel - Jen Sookfong Lee

Jessica Campbell is sorting through her recently deceased mother's belongings. She wasn't expecting to find two dead bodies in the bottom of her deep freezers. As a foster mother, Donna Campbell had many children come into their home over the years. Jessica can remember two teenaged sisters who lived with them almost thirty years ago. Casey and Jamie Cheng were two very troubled and defiant girls who everyone assumed had just run away. Jessica can't believe her mother was capable of something like this, but as she learns more about her mother's childhood she realizes that she didn't know her mother as well as she thought she did.

This was a compulsive read for me. It is very well-written. I enjoyed going back and forth between the past, learning about the Cheng sisters, their upbringing and what lead them into foster care, and the present where Jessica is trying to figure out why her mother would murder two of her foster children. The ending wasn't what I was expecting, I wanted more.
