I jsut finished "Seveneves" audio book. It started out like near future speculative fiction, somewhat in the vein of a more ambitious "the Martian" and became a lot more in the final third. It was pretty good.
2 more sci fi books from this century I strongly recommend are "Spin" by Robert Charles Wilson, and "The Three-Body Problem" by Liu Cixin. Both are kind of Grand sci-fi trilogies, but the first books in particular are enthralling (the second and third books of three body problem also keep finding new ways to keep you hooked).
Any recommendations in similar veins?
