"A Madness Of Angels" is interesting, as it is written in first-person-perspective, of someone who is both 1) from a different morality worldview than ours, and 2) actually insane. It's Modern Fantasy rather than Near-Modern Sci-Fi, but there's a reasonable amount of having fun trying to figure out what's happening not in a whodunnit way but in a "peel back the perspective layers" way, which is kinda-sorta like a "peel back the reality/dream layers" way of Inception.

That stated... It's first-person free-writing. While you definitely get used to it as you read it, it's NOT an easy or light reading to get into at the start.
