Isaiah 24-27, Daniel 7-12, Ezekiel 37-41, Zechariah 9-12 and Revelation, right?
I'll assume so, I haven't looked up chapter and verse to verify, but that sounds right. There's another one in the Apocrypha too, 2 Esdras.
Apocalupsis (Gr.) means revelation. Revelation of ... ?
It means revealing things that would otherwise remain permanently hidden because they're not accessible to human reason. I take that to mean there's no evidence for them, and I like Christopher Hitchens' idea about that: what can be asserted without evidence can be dismissed without evidence.
I believe the Quran borrows eschatology from the Abrahamic faiths, does it not?
Yes, and a lot more too, it's heavily derivative of biblical tales, to the point that I think it could fairly be called plagiarized, but nobody cared much about that 1400 years ago. It's also spectacularly dull and repetitive, a difficult read, at least in the English translation I've seen. For all I know it may be sublime poetry in the original Arabic, the local Islamic proselytizer, Torch light or selfsame or eanassir or whatever he's calling himself these days (I don't pay much attention to him) would no doubt claim it is, but that's no good to people who can't read Arabic. Gotta wonder about the intelligence of a deity who provides a message that's inaccessible to most of humanity.
From my reading of it, the Bible (Book) is about reconciliation and regeneration.
Only if you cherry pick the parts that support that conclusion. A lot of it's pretty horrible, especially in the Old Testament, but the Bible is a sufficiently large and complex text that you could probably find support in it for almost any position you'd care to take. I like 1 Thessalonians 5:21: "Prove all things; hold fast that which is good." The skeptic's mantra.
