2016 was pretty good for LNs.
Is It Wrong to Pick Up Girls in a Dungeon got past where the anime left off and the story just got better. Vol 6 might be the best in the series.
The latest arc in Accel World seems to never end, but it's been good. So long as I don't think of the game they're playing as software, but as magic.
J Novel club let me read a bunch of novels for a lot cheaper than I normally would've been able to. That was a godsend when I was traveling a lot last month and had multiple layovers and train rides.
I haven't gotten to Grimgar yet (plan on it), but I've enjoyed every series I've read from J Novel Club. Grimgar and My Little Sister Can Read Kanji got me to sign up, but The Faraway Paladin is the one that's really impressed me. It reads like a cross between an LN and a western fantasy novel. I'm curious where it's going to go.
Also, the Mixed Bathing in an Alternate Dimension surprised me. I was expecting stupid wish fulfillment in another dimension but got the beginnings of a hero.
