That summer, the three girls had the world at their feet. Now, one is missing.

On a summer's night in 1994, 16-year-old Flora Powell vanished from her sleepy seaside town. She left no trace - only heartache for her mother and her sister, Heather.

And one is a murderer.

Twenty-five years later, Heather walks into a stranger's house. There, the loving wife and doting new mother kills two people in cold blood.

So only one remains...

Jess is sent to report on the case that shocked the hometown she left behind. But it's anything but business to her. She was like a sister to the Powell girls, until the summer that tore them all apart.

Can Jess find the key to both their mysteries?

Or will her search reveal a darker side to the place she grew up - and put her in danger?
