It’s intense.

Well written.

There are plot twists that surprised me.

Jenna Gray has rented a spare cottage in a small Welsh town on the coast.

She’s timid and doesn’t interact with many people, just her landlord and a woman at a local shop. She’s running away from the death of a child.

In parallel, Detective Inspector Ray Stevens and a female rookie are working on the case of a young boy killed in a hit-and-run right in front of his mother.

Inevitably, the story reveals itself.
