As I am compulsive reader I could take whole page for myself writing titles, so I will try to restrain to just few. Any book of Sir Ronald R. Tolkien - be it Silmarillion or LotR or essays. I do dig some of Sir Terry Pratchett's books to, but he is sometimes a little to nihilistic. Or rather was, RIP Tad Williams "Memory, sorrow and thorn" trilogy - slow in action but packed with emotions. G.K. Chesterton's books. Or newest discovery - Tom Kratman's Carrera series.
@dampf Check out latest revival of Tomek Kołodziejczak - I am hardcore fan of his Dominium Solarne, but new universum he started with Czarny Horyzont is also great. Like korgard's on steroid with of a twist.
Throne of Glass is my favourite series! The first is kind of slow building up the story for the rest of the series. My favourite within the series used to be the second, Crown of Midnight, but since the fourth came out my feels!!! Queen of Shadows is my favourite. I can't wait for the fifth to come out in September =)
