If you read fantasy at all, you must read Robin Hobb. She is the best and no other fantasy authors compare.
So far she has written 3 trilogies set in the same world.
The first one is the Assassin Trilogy, featuring the 'hero' Fitz from a child of 6 to a young man.
The second one is the Liveship Traders trilogy, not featuring Fitz but mentioning his part of the world, and with one common character.
Finally there is the Tawny Man trilogy, again featuring Fitz as a grown man in his 30s or 40s.
They are just fantastic. The characterisation is beyond belief, all the characters are complicated and well rounded - a character can be really cruel and evil, yet she still enables you to have compassion for them, and best of all she doesnt' treat you as an idiot but leaves you to work things out for yourself.
She has just written the first of a new trilogy, set in a different world. I have it but have not read it yet as I am reading Harry Potter.
