Oh boy, you've come to the right place. I know it's been said before, but anything by Brandon Sanderson is good; he's basically the epitome of modern high fantasy. Steelheart is his superhero book, except all the superheroes are badguys; Mistborn is his urban fantasy; The Stormlight Archive is his suoer hugh fantasy; with a softer magic system and more distinct realms within the world; and Skyward is his sci-fi with spaceships and almost sentient AI. Keep in mind Stromlight Archive and Skyward are unfinished series, but they're both still very good. My favorite was Stormlight, it's the biggest in scope and it's more complex than the other ones, and when everything comes together, the plot becomes really exciting. Mistborn was my least favorite, it's one of his earlier works, so i found a few bits to be contrived and unpolished. Next author is Mercedes Lackey. Her stuff is a little drier, it's a little slower, but the payoff at the end is unmatched. She really takes the time to build her plots and develop her characters before rushing to any other part of the story. So sometimes you're going to have parts of tolkien-esque description about how a nail was bent at precisely 37° and the light reflected off the surface on to an antpile where 6 ants crawled across it, so if you like that, you're in luck. Anything by her is good, but the best of her stuff is the Obsidian Trilogy and the Enduring Flame Trilogy, both taking place in the same universe and both co-written by James Mallory. To me, there is no better example of character development than these two series, so if you're in the mood to read an average teen turn into a legendary hero, definitely pick these two up. Next is Tunnels, by Roderick Gordon. This book is very creative; it's about this miner kid that discovers a secret society that's been living underground for milinea. It's pretty action-oriented, so the plot moves fairly quickly, but the premisis is so unique that i haven't found anything quite like it ever since. There's indiana jones-y exploration parts, there's survivalist parts, there's sneaky espianoge parts. It's like a mix between Journey to the Center of the Earth and like James Bond, and there's a lot of cool elements that stem from the worldbuilding. I gtg rn, but i has more
