Dark Waters — Lorraine Kennedy

Bayou Landing is the picture-perfect southern town but beneath its charming exterior, there are dark secrets and unspeakable horrors. 

Twenty years ago, two children disappeared without a trace, leaving Bayou Landing and Kara Savoy changed forever. One of the children taken was Kara's twin brother. Kara can see dead people and she is determined to use her gift to find out what happened to her brother on that fateful day and to uncover the horrifying secrets lurking beneath the civilized exterior of her small hometown. 

The second child to disappear that year was Special Agent Colin Reid's sister. Colin is also determined to unravel the mystery, but he doesn't want Kara's help. When another child goes missing, Kara must convince her childhood friend to let her help, but that won't be easy. Colin doesn't believe in Kara's gift. Will the ghosts of the past lead them to the truth or will Kara and Colin be sent to their graves?
