I can second the New Sun series. The bizarre thing about this series is that it is a hole in my memory. I can remember reading it, I can remember liking it, and I can remember little snippets, but I can't remember most of the specifics. I've read the series twice, but even the second reading hasn't resolved this failure to recollect. Ironically -- likely on purpose -- that's the point. The series centres on an unreliable narrator, which is a part of the charm. You forget moments because the narrator wasn't clear. The narrator wasn't clear because the he didn't understand what he was seeing. You have to re-read the series, perhaps several times, to figure out what's truly going on.
