A haunting thriller about a troubled married couple whose vacation to Paris leads them into a nightmare.

Mark and Steph have a relatively happy family with their young daughter in sunny Cape Town until one day when armed men in balaclavas break in to their home. Left traumatized but physically unharmed, Mark and Steph are unable to return to normal and live in constant fear. When a friend suggests a restorative vacation abroad via a popular house swapping website, it sounds like the perfect plan.

They find a genial, artistic couple with a charming apartment in Paris who would love to come to Cape Town. Mark and Steph can't resist the idyllic, light-strewn pictures and the promise of a romantic getaway. But once they arrive in Paris, they quickly realize that nothing is as advertised. When their perfect holiday takes a violent turn, the cracks in their marriage grow ever wider, and dark secrets from Mark's past begin to emerge.

Deftly weaving together two complex and compelling narrators, S. L. Grey builds an intimate and chilling novel of a disintegrating marriage in the wake of a very real trauma. The Apartment is a terrifying tour de force of horror, of psychological thrills, and of haunting suspense.
