When Heather Oxon goes missing during a cross country run her entire prep school and the affluent community of Waterbridge are in turmoil. Popular, pretty Heather who at sixteen had her whole life ahead of her. Why would she run away?

Only two weeks later Heather’s body is discovered washed up on the bank of the River Severn several miles away from the rural estate where the run took place.

Abbie Parks is trying her best not to think about the missing girl. She’s busy renovating her large home and trying to hold together the crumbling façade of her marriage. But since Heather went missing something has changed in her own teenage daughter, Pippa, who was there on the run that day. Who was best friends with Heather. Pippa is withdrawn, sullen. Surely she is just grieving for her fallen friend.

But an autopsy report reveals that Heather did not drown. She was dead before she fell into the water, succumbed to a fatal anaphylactic reaction to peanuts. An allergy which was well known within her school, her peers. An allergy Heather has managed all her life. Now the police are no longer investigating a suicide – it is a murder enquiry.

Soon all the secrets of Waterbridge’s residents will be brought to light and Abbie’s seemingly perfect life will be questioned. But none of that matters to Abbie so long as Pippa is safe, so long as Pippa isn’t involved in Heather’s murder. For her daughter, Abbie would do anything.

Allie, Stacie, Diana, Emily and Gail have been by each other's sides for as long as they can remember. The Fierce Five. Best friends forever. But growing up has meant growing apart. And little white lies have grown into devastating secrets.

When Gail invites the increasingly estranged friends to reunite at her Scottish cabin, it could be the opportunity to mend old wounds and heal the cracks in their friendship. But when a freak snowstorm rocks the cabin and one of the girls is found dead on the ice, their weekend away becomes a race against time - and each other - to get off the mountain alive.

And in the end, whose story can you trust, when everything was founded on lies to begin with?
