Sound--The Delta Girls--Book Two

Five extraordinary sisters discover that they each have a unique talent, an extra-sensory perception that enables them to see what others can't. It makes them incredible, it puts them in danger, and it brings them closer to learning the secrets that have haunted them their entire lives. These are the Delta Girls.

Serena and her sisters read a private letter their father wrote to their mother, revealing a clue about his disappearance that they never knew about before. But as they struggle to gain further insight through their sensory visions, trying to solve the mystery continues to prove elusive.

The Delta Girls try to move on, balancing their supernatural abilities with the daily trials of being teenagers. Studious Serena teams with the classroom outcast, Lara, and her charming brother, Damon, for a school science project. They end up studying more than they bargained for, though, when strange noises come from rooms in Lara and Damon's house. There are voices, but only Serena, with her special powers, can hear them. This is until the trio experiment with Electronic Voice Phenomena (EVP) and are able to record and hear them on the computer.
