The details I remember are very hazy.
What I remember is that it was a young adult horror novel from the late 80s / early 90s.
Two kids live in a town, and the town has a section where the woods are haunted and very bad things happen if you go into them. There is a lot of snow in the book and the cover of the edition I remember had snow on it as well.
At one point in the book, they sneak out and go into the haunted woods at night.
That's about what I got. I don't remember why they do anything or what happens, but I remember reading it at least twice and liking it.
Update - [a bit more info]:
I know it is not from the Goosebumps series - the content was for slightly older kids. It is possible that it is from the Fear Street series or some other RL Stine, but I looked through the titles and plot summaries and none of them seem to fit. I'm fairly certain it wasn't Christopher Pike, and until searching for this, I have no memory of ever hearing of the Point Horror series. I don't think it was actually part of a series at all, but I wouldn't stake more than a nickel on that.
Also; I hesitate to put this, because I think it is likely a corrupted memory, and may make things harder; but in the absence of any quick answers, I'll give it a shot. I think the title was something like Night(mares | time ) in Ghostland
That could be way off base, but for some reason, that title strikes a chord in memory. I hope the extra info helps.
