So there's a great bundle up at the moment for Greg Bear, one of the big names in 80s and 90s SF, and it's open to the world, raising money for SFWA.
27 books all up, including both SF and Fantasy short fiction collections, his big space epics Eon & Eternity, the alien invasion duo The Forge of God & Anvil of Stars, several horrors, near future cyberpunk in Queen of Angels & Slant, the Hugo and Nebula winning Blood Music, it's got something for everyone.
It also includes his underrated Songs of Earth and Power duo, which is a really different take on the Sidhe, much more modern in feel.
