The River Mouth

Ten years ago, fifteen-year-old Darren Davies was shot dead at the river mouth. The killer was never found.
Now, Darren's mother Sandra receives a visit from the police. Her best friend Barbara Russell has also been found dead, out in the bush. And Barbara's DNA matches the DNA found under Darren's fingernails.
When the investigation into Darren's murder is reopened, Sandra begins to question what she knew about her best friend. As she digs, she discovers that there are many secrets in her small town - and that her late son had his own, too . . .
