Fantastical historian
I have two main plot lines in my book, but they take place in the same city and they (and the characters in them) interact and have a theme in common (humans' varying attitudes to the non-humans in my world). I prefer that to completely separate PoVs, e.g. characters who don't meet or even live on the same continent until well into the book, which I sometimes find hard to get into as a reader. Not always (GRRM and Richard Morgan write well enough to keep me reading), but it's one more barrier.
