Farseer Trilogy should really come with a disclaimer to not read if you're depressed or going through a difficult time. The author is very skilled, but that series was analogous to being kicked repeatedly in the balls, given how much the main character goes through.
There's like five trilogies in the same world, well worth reading the whole thing. The first is probably the worst in terms of what the characters go through, but the really nice part is how later books build on what happened here.
My brother has coined the term Depression Olympics between this and The Stormlight Archives for what the characters go through and Farseer makes Stormlight look like childsplay
