1983: seven teenagers go camping overnight in the woods, but only six return. Where is Aurora? Which of the six know? Is one of them a killer?

The novel picks up the story in the present day. A child playing by the river uncovers a body that has lain undisturbed for 30 years and a police investigation is launched. Cutting between the work of the detectives and the events of 1983, this is a well plotted and engaging novel that kept me turning pages long into the night. There are plenty of twists and turns along the way and lots of complications to keep the enquiries moving along. Although some of the flashbacks didn't seem that relevant, they all helped to set the scene and explore the six characters who, now in their 40s, find themselves at the centre of a murder investigation. The group dynamic is interesting and realistic, even if the police officers involved aren't particularly distinctive.

I'd recommend this to anyone who likes their murder mysteries with plenty of long-hidden secrets and lies. It's cleverly thought out, pacy and will keep you reading until the end.
