This really packed a punch. I enjoyed moving back and forth between the two timelines and while some of the things depicted were absolutely horrific, it never felt like it was gratuitous or without purpose. This was like two stories woven into one. 

The first was a character study of an apartment building filled with haunted people, living in a (lightly) haunted building. Sana, the main character, is adrift after the death of her sister and mother. She investigates the residents of the building and its history, digging deeper and deeper until she discovers the horrific story of the builder of the home. 

The second timeline follows the original home builder, his family, and the tragedy that befalls them. It’s dark and ominous and you can’t help but root for the safety of the main POV in that timeline even knowing that things are not going to turn out well. Finally, the two timelines merge in an exciting and satisfying ending. 

This was beautifully written and haunting.
