Every book review on HorrorExchange.com scores 8 facets, each on a 1 to 5 scale with half points allowed, and each with a short comment explaining the number. This guide covers what each facet measures, what a high or low score tends to feel like on the page, and a real example from one of Yvonne's published reviews. The overall rating (0 to 5) starts from the facet average, but Yvonne has the final say on how the whole book landed. To see how the whole system fits together, head back to How We Review.
One thing to keep in mind: a low score doesn't always mean a bad book. Sometimes a facet just isn't what the book is going for, and the comment will say so.
Prose / Writing Style
This is the quality, flow, and accessibility of the writing at sentence level. It does not judge the plot, only how it feels to read. Plain, fast prose can score as well as lyrical prose if it suits the book.
A 4 or 5 means the words carry you along without effort. A 1 or 2 means you're fighting the page, or the writing needs a firmer edit. In Black River Orchard, Yvonne gave it 5/5 for prose that is punchy, chaotic, and functional. Even at 640 pages, the story never dawdles, and she burned through it in three days. University got 3/5, since at nearly 500 pages her paperback badly needed a tighter edit.
Vividness
Vividness asks how clearly you can picture the world and its characters. Does the writing put images in your head, or do you have to fill in the gaps? It is different from Prose, because a book can read smoothly and still leave the room and the people undefined.
High means you could almost see the place and the faces. Low means you're working to imagine them. For a sense of why it matters, Yvonne said some of the imagery in Black River Orchard gave her real stress and anxiety. That is what a picture you can't get out of your head does for horror.
Storytelling
This covers narrative structure, plot construction, and pacing; momentum lives here. It measures whether the story is built well, not necessarily whether you like where it goes.
A 5 means the structure earns its choices and the pages turn themselves. A 2 means the middle sags or the plot stalls. Horns scored 5/5, with Yvonne saying its non-linear structure could have been a gimmick, but the mystery unspools gradually and the backstory adds emotional weight. University scored 2/5, because it starts strong but gets bogged down in the middle, more interested in showcasing one deranged scenario after another than moving the plot forward.
Character Voice
This is the depth, growth, and distinctiveness of the characters. It asks whether they feel like people with their own inner lives and their own way of speaking.
High means you remember characters long after you close the book. Low means they blur together or tip into caricature. Black River Orchard earned 5/5 for Dan's slow-burn corruption at the center and a teenage daughter with a distinctly contemporary voice. University got 3/5. Yvonne found the believable, likeable group easy to root for, but the corrupted characters are so over-the-top they become caricatures.
Psychological Dread
This is the buildup of internal fear, anxiety, and unease. It is about what happens in your head while reading, not about how much blood is on the page.
A 4 or 5 means you feel it: a knot in your stomach, a reason to put the book down for a minute. A low score means the book either isn't aiming at dread, or the dread quickly wears off. Black River Orchard scored 4/5, and Yvonne says it gave her stress and anxiety as the stakes rose quickly. Husks, on the other hand, got 3/5; it isn't a scary book and isn't trying to be, with a quieter unease that is more about what you ask yourself while reading.
Villain Quality
This measures the effectiveness and menace of the antagonist. It does not demand a monster, because a villain can be a person, a place, or even a force.
A 5 means an antagonist who stays with you. A low score can mean a weak threat, or a book with no villain in the usual sense. Horns scored 5/5, since its real antagonist is slowly revealed as something monstrous. Husks got 3/5, because there is no traditional villain or monster and the weight comes from a choice the main character has to face.
Surprise Factor
This is unpredictability, twists, and shock value. It measures how well a book keeps you guessing, and a surprise that feels earned counts for more than one that is only loud.
High means you didn't see it coming and it still makes sense. Low means the book is predictable, or its shocks run out of steam. Horns scored 4/5. Its jumping timeline keeps the truth under wraps longer than Yvonne expected, without withholding information just to withhold it. University got 3/5 for leaning on escalating shock value over real twists, and once you catch the pattern, the surprises stop landing.
Social Commentary & Themes
This is the depth of the social, political, or cultural ideas, and how well they're built into the story. Heavy-handed messages score lower than ideas that grow out of the characters.
A 5 means the horror is about something. A low score means the book skips the chance or misses it. Black River Orchard scored 5/5 as it digs into the divide between haves and have-nots, using the supernatural to show how deep-seated resentment turns monstrous. University got 2/5, because there was a real opportunity to say something about conformity or higher education, and the book mostly just delivers graphic content.
