The Sanatorium

How it reads

The Sanatorium is thriller (locked-room psychological thriller, specifically), and its dominant mood is eerie. It's atmospheric and uncanny, with a sense that something is wrong. It moves fast: plot-driven and hard to put down, the kind of book that carries you along even when you're tired.

It's set in the wilderness or at sea, in the present day, told in the third person, staying close to one character. Its central concerns are secrets, survival and loss and grief. In weight it sits in the middle: substantial without being heavy going.

It stands alone, so there's nothing else you need to read first or after. The ending resolves happily. It's well known, the kind of book most keen readers have heard of.
