Time to nerd up this shit:
Frank Herbert's Dune
Ender's Game/Ender's Shadow (both are equally as good and are set in the same universe so yeah, technicality but fuck off)
Snowcrash (this is actually a really "shit" novel when you first read it, it's standard cyberpunk stuff and even the main character is the most cliché'd shit ever, he's a japanese american who walks around with a katana and he's named HIRO PROTAGONIS. Then you realize it's a goddamn satire on the entire scifi genre)
Neuromancer
A Murder of Crows (best book in the whole A Song of Ice and Fire series imo, tho the whole series is excellent)
If we're talking short stories:
At The Mountains of Madness
The Valley of Fear
Wings in the Night
The Langoliers
The Hours of the Dragon
