Review: Room: A Novel
Someone saw me reading and wanted to save me from the hassle of getting to the end by spoiling it.
I think I got as far as the child's first memory of the patterns on the walls or ceiling. Up to that point, it was an uncomfortable read, and I couldn't figure out why that was. And then it was spoiled and I realized that person had saved me a lot of valuable time because the ending was predictable.
