I voted, but you are open to lots of different genres, so let me also suggest a few books that excellent, fun reads too.
1) Sabriel by Garth Nix (high fantasy but not at all dense and so compelling, rated teen but adults love it just as much).
2) Red Sister by Mark Lawrence (high fantasy which is longer and a bit more dense, but so addictive; about an unusual girl who is suspected by her superstitious small town of being dangerous and thus sold to a nunnery which is not at all like those on our planet but a nunnery that trains to be female knights of a sort to defend a relic of power; set in the world of Abeth which is very slowly loosing its sun and is now without tech, though once it had tech far beyond anything we have. This is one of the most addictive fantasy/sci-fi series I have ever read)
3) The Bone Season by Samantha Shannon (alternative reality to our own, one in which a percentage of people evolved have TP & TK powers but the majority are jealous and discriminate against them; love interest develops between enemy to friends).
4) The Winter People (thriller)
5) The Eight by Katherine Neville (mystery)
6) The best M. Atwood novels (in my humble opinion) are Cat's Eye and the Oryx and Crake trilogy--both winners of multiple awards
7) My favorite speculative fiction: The Ten Thousand Doors of January by Alix Harrow and All the Birds in the Sky by Charlie Jane Anders --both winners of multiple awards
