Kushiel's Dart (but not the sequels). The worldbuilding is delightful.
How strange! I had the exact opposite experience. By mistake I read Scion first. I then went in order, got to the end, and looped around to Dart. I thought Scion stood on its own extremely well and have been recommending friends start with it; I was almost unable to finish Dart and dismissed it as "Guess she hadn't learned how to write yet".
(My friend who started with Scion on my advice also ended up enjoying them all except Dart, and I suggested to Alicorn that she not start with Dart, she refused my suggestion, and then she disliked Dart and didn't read the others which was my prediction all along.)
Kushiel's Avatar continues to be my favorite of all of them, and the new Naamah series isn't bad either.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that exposure to LW ideas makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
