The Stormlight Archive Though I'd recommend another series first (probably the standalone "Warbreaker")
Most of his books are loosely set in the same universe (a small globular cluster/dwarf galaxy), so each series is completely self-contained but there's a very subtle meta-plot going on (which took the fans 4 books before we realised a star cluster was appearing very often and didn't we see that beggar before?) that only really gets started in Stormlight Archive, which is supposed to act as that meta-stories "spine" (though it's still in the background).
