The Sum of All Men (Book One of The Runelords) by David Farland - incredible high-fantasy that introduced me to the genre and one I come back to time and again. The magic system is rock solid and as scientific as the best Brandon Sanderson system, the characters are engaging and multifaceted, and the ethical quandaries they face are complicated in a way that has you reassess your own values.
Assassin's Apprentice by Robin Hobb - ever wanted to be within the mind of a plausible, real, human, flawed assassin? Look no further! Fitz is the most loveable (and hateable, simultaneously) character I've ever shared headspace with, and if you enjoy this book there're a dozen more in the series that are all bangers. Two magic systems, both well developed if not as rigorous as the one in The Sum of All Men, complement one another well, and you get to explore the effects magic can have on culture and society.
Writers of the Future Volume 40 - an anthology that includes 12 short stories from upcoming sci-fi and fantasy writers and 3 from seasoned veterans. The 12 short stories have won out from a contest with literally thousands of submissions, and cover the gamut of speculative fiction. Odds are, the next Brandon Sanderson (one of the judges) or Orson Scott Card (another judge) or Patrick Rothfuss (winner of Volume 16) has a story amid these very pages.
Sidenote: Writers of the Future was initially created by L. Ron Hubbard, founder of Scientology. However the judges are not scientologists, and winners are not invited to 'convert.'
Honorable Mention: The Name of the Wind by Patrick Rothfuss - it breaks every rule of fantasy fiction, but does so with flying colors. Not included because you will fall in love with the world, and the series isn't, and likely never will be, finished.
