Utter brilliance. I could not stop reading. Original premise, sublime execution, chilling ending. I might have finished the review here, urging everyone to read the book, but it's worth pointing out a couple of the novel's strengths.
The book is about a family of four, the Bakers, spending their vacation together in Haven, a house inherited from a little-known aunt. The story thrives on subtlety and characterization. It reads like a slow burn if you fail to pick up on clues, those hints hidden in the details; no shame if you do: the book has many moments where a parent's thoughts pass seamlessly into dark and disturbing thinking, where a wife starts losing her mind with no fanfare, where teenagers, already uncanny valley dwellers, plan to kill their siblings, incapable of realizing their own descent into resentment and despair.
But it's just thinking, right? Wrong. The family is caught unawares by a long-term plan of revenge by the house's builder. The house is meant to dive into the worst aspects of a person, and bring out the buried pain, the self-doubt, the insecurities, the darkness already there. The author pulls this off by telling the story in character-driven mode. Think of aerial photography: it can't show you the caves and the tunnels of an area - but they're there, waiting to capture unsuspecting victims; you have to go there and discover them yourself or hire a guide. Similarly, in "Haven" the horror is buried under familiarity, calmness, lack of fighting; you have to allow the author to show you around these people's mindcaves and tunnel a way out to the surface, through hard-won insights into parenthood, adulthood, and married life. And then comes the third part of the book, when thoughts become actions. However, don't expect gore, depravity or perversion: the house is meant to encourage already existent flaws, it does not take away choice, it influences... subtly. Personalities melt into shadows, minds are sucked into background history: a history of love and revenge, told with great empathy through the aunt's eyes.
My favorite moments were two: when we realize the implications of the house's name, its origin and its purpose (always implied); and the deeply unsettling ending, not even shown on the page. In both cases, I was chilled to the core. Mia Dalia is a genius.
And the cycle goes on.
