Unsound

Arran went missing in Edinburgh fourteen years ago. The last time his parents saw him he was withdrawn and on edge where he'd once been happy and carefree. Still searching for their son, they turn to their last hope, true crime podcaster Cal Lovett.

Cal begins looking for answers, but is distracted by his sister's murder trial. He's so close to getting the justice Margot deserves. Can he finally leave the past and Margot behind?

As Cal unearths disturbing evidence about Arran's fate, he suspects the young man's close-knit group of university friends are keeping secrets to protect each other. It seems old loyalties don't die easily. But they can't all stay silent forever

An unputdownable crime thriller perfect for fans of Jane Casey, Cara Hunter and Neil Lancaster.
