Currently Reading "The stormlight archive" series by Brandon Sanderson (still on the first book "the way of kings" though). I already read most other books of the cosmere (Sanderson's Universe where most of his books take place). Highly recommend it!
For me definitively the soundtrack of Boneworks (which is also the best VR game I know). Especially its main theme ("Bone Theme") and "Who am I"
Some more awesome OSTs in no particular order: Minecraft, Banjo-Kazooie / Banjo Tooie, Witcher 3, Risk of Rain 2
