It might not help you judge whether the pace will be manageable for you or not, but the original nomination has sample pages which you could try reading to see whether your grammar is about right.
Of course, the first few pages are always quite hard as you get into it.
I guess the best you can do is read the first three pages (in the nomination post) and ask yourself if you are prepared to do 15 pages per week.
Of course the first few pages are always harder, since you get used to the author’s writing as you read, and certain terms are often repeated that you had to look up before.
It is totally up to you, of course. If you feel like reading it, go for it! Wild abandon and whatnot.
I do remember thinking that maybe I would’ve enjoyed the reading a bit more if I didn’t start off trying to read as difficult books as I did, though. Reading (much) above your level makes it harder to enjoy the writing and I ended up getting bored with the chore of slugging through word by word. Whether this would be the case for you and キノの旅, you will have to judge for yourself.
That’s always a problem for me too at first, it usually gets better the farther I go into a book/series and get used to each character’s personality and speech and whatever though
I mean, when you don’t yet know what the heck is going on, it’s a bit irritating.
I just joined the beginner book club a couple months ago for 時をかける少女 and it’s a great experience. That’s the first light novel I’ve read where I’ve had good comprehension and not given up on it, both thanks in large part to the club.
I don’t think there’s any real criteria for something being a light novel or not. They mostly have some typical characteristics, but some light novels don’t follow those and some normal novels can also be kind of similar sometimes. The books that are called light novels… are light novels. That’s all I’ve managed to figure out.
