Only ever met one other persons who had ever even heard of her but I have a particular love for the works of Jaqueline Carey. The Sundering duology is gorgeous moral greyness with epic fantasy scale and yet personal characterization. The Kushiel series (the parts I have read so far) is the intertwining of political thriller, historical fiction, magical realism, BDSM romance, and again, has both epic scale plot and personal characters. I recommend the Sundering to everyone and Kushiel’s Dart to anyone old enough their mother won’t come around and attack me for exposing their son/daughter to the sexual parts of the book. There are others but those ones always come to mind when I see/hear this question.
