I know someone who is a YA Librarian (Young Adult). She uses lists of books that are specifically aimed at teenage readers. I don't have access to these lists myself, but you could google "YA reading list" This was the top result when I googled it: https://www.goodreads.com/list/tag/young-adult good luck
Fiction you say... this has to be one of the best out there! The Legend of Drizzt Series by R.A. Salvatore Based on the D&D world Forgotten Realms. This series consist of 26 books currently, I have read 13. They have all been so Good! It's not teenie stuff, but a wise 14 and above y.o geek could find it very interesting. While there is a lot of adventure, fighting Orcs and Trolls and other evil beings, what really got me into the series is the main character Drizzt Do'Urden. Drizzt is a Dark Elf (drow) born in an underground Dark Elf city called Menzoberranzan. He is one of the best fighters, with his double swords. Dark elves are evil beings, they only care about their own good and they are ready to stab their own mother (which they often do) if that is necessary. Drizzt is different. This book is about how Drizzt leaves the evil Menzoberranzan, to the above world. He meets other adventurers and they build a very strong fellowship. The loyalty and morals in this fellowship are very strong. The sacrifices the members of the fellowship are ready to bring for the safety of other fellowmen are enormous. Drizzt also finds a companion, black panther, named Guenhwyvar. He becomes Drizzt's best friend and the strong spiritual connection between these two is very well described in the book. Drizzt is ready to die for his companion, and so is Guenhwyvar ready to die for Drizzt. That's why I love the series. It is about good values. About things that matter the most. Drizzt often describes his thoughts and ideas in the book, and when I was reading it, I agreed with him so much. When this happens that you completely agree with the writer and enjoy the story, you will get very hooked in. Yeah, anyways, story about friendship, fellowship, loyalty, honor, adventure and a touch of slashing goblins and trolls and other evil beings.
I appreciate the classics. Shakespeare, Sophacles, Petrarch, as well as more recent authors like Steinbeck, Dickens, and Sir Arthur Conan Doyle. I'm currently in the middle of Dickens' "A Tale of Two Cities" as well as Shakespeares' "Othello" which I'm reading for my AP Literature class. I also recently finished the "Leviathan" trilogy by Scott Westerfeld which is a fun steampunk take on World War One, as well as the "Charlie Bone" series by Jenny Nimmo which is a little difficult to explain, but if you like Harry Potter, you'll probably enjoy it.
And ofcourse Terry Pratchet's Discworld!! I must have read about 20 books from that series. Now I mostly read difficult books. Currently I am reading Intelligent Investor by Benjamin Graham, Margin of Safety by Seth Klarman and Invesment Banking: Valuation, Leveraged Buyouts, and Mergers & Acquisitions by Joshua Rosenbaum and Joshua Pearl. All very difficult finance books. But I love to read, and I used to read a lot of fiction and fantasy when I was younger.
