A woman on the brink travels to a remote writers' retreat to uncover the secrets of her past – and lands herself in a deadly situation that could destroy her future.

Kate arrives on the wild, remote island of Rathlin in the freezing Irish Channel for a ten-day writers’ retreat. Plagued by memories she can’t unravel and desperate to understand the breakdown of her marriage, Kate is determined to leave the retreat with answers.

As the retreat’s director uses techniques that tap into the eerie mythology of the island, Kate becomes increasingly fascinated by him and her surrounds. But as the temperature plummets and the strange therapy intensifies, her memories unspool. Triggered into a series of disturbing flashbacks, Kate realises her past hides a frightening truth, but can she trust her own mind?

Faced with dark secrets and duplicity, Kate must unlock the answers she’s so desperate to find – and survive the danger she has unwittingly walked into.
