Book recommendation

[Steel Accord 6,660]

Hey guys I thought I could maybe pick your brains for a recommendation. See, awhile back I read Fallout: Equestria and since then, nothing has matched it. I know that might sound sad and it's not like I don't read other stuff. Try as I might though, there hasn't been a story I've read in the printed letter that has made me emotionally invest as hard, blew my mind with its plot turns, fall in love with its characters, and kept me nail bitingly tense at the climax. It's the first story I read that made me jump up and shout while reading it. I'm looking for a book that will do something similar. Time commitment is not an issue, if anything I'd like a nice long book for me to really travel with the characters, which brings me to the specifics so let's get down to brass tax.

I’m looking for a book about a small group of allies undertaking a grand quest. Maybe the quest isn’t clear at first or maybe it starts small and grows into something more. As a matter of fact, escalating from a humble road trip to saving the world is really kind of the key feature I’m looking for. One of the only stories that came close to Fo:E for me was Neuromancer, precisely because it started with cyberpunk hackery in a slum and ended with pretty much the achievement of the Singularity.

Got any recommendations? Fantasy in particular would be nice but sci-fi or other would be good too.

P.S.: Not LOTR or Narnia. They are great but I know them already.
