I received this book for free from NetGalley in exchange for an honest review.

The Thin Place centered around the dark history of the foreboding Scottish estate, Overtoun. It follows the story of three women from different times whose lives will somehow intersect.

The story starts with Ava, a television journalist, who decided to investigate a bridge near the Overtoun estate where many dogs have jumped to their death.  She soon obsessed to uncover Overtoun's dark history, putting a strain on her relationship with her family, partner, and her job.
We're also introduced to two other women — Marion and Constance. Marion, in 1929, she married the lord of the manor. It tells her story of courtship and marriage plagued by loneliness, misery, and tragedy. Constance, a sickly young girl who lived in the manor in 1949 with a devoted mother.

A compelling and gripping thriller with its gothic and creepy atmosphere. The Thin Place is slow paced with realistic and well-written characters. Ava is not a likeable character. She makes a lot of bad decisions. I found myself drawn to Marion and Constance. Both of their stories are heartbreaking and sometimes uncomfortable to read. A book filled with intrigue and secrets, some were predictable. The slow build up of tension was so satisfying!
Overall, The Thin Place is a captivating read with a perfect mixed of mystery and suspense.
