Obsidian - Jennifer L. Armentrout Not bad - at all. The story is not bulletproof, and that's a shame, but "Obsidian" was so entertaining that I was able to turn off my critical "waaaait, why didn't..."-commentator track. It's a fun story, I absolutely love the quite random expressions and metaphors the author uses all over the place, and it actually leaves quite a bit to the imagination - something that is clearly underrated. I wish I could had read this at 15.
