The following caught my eye:
The Witcher series by Andrzej Sapkowski. At least the first 2 or 3 books.
American Gods by Neil Gaiman
A load of Mistborn and The Reckoner series and standalones by Brandon Sanderson
The Long Cosmos by Terry Pratchett & Stephen Baxter
V E Schwab's A Darker Shade of Magic and sequel, along with the standalone This Savage Song
Maurice Druon's The Poisoned Crown (Book 3 in The Accursed Kings). A historical, but one of the influences on A Game of Thrones.
