Frank Herbert's Dune, Robert Jordan's Wheel of Time

Shadowhunters is one I've been wanting to read that has both a movie and TV series, bonus points for que.er representation. it's about a hidden society of human-angel hybrids in the modern world who hunt demons and shit

Unwind is a really really really good series and one of my favorites! has no TV show or movie but it's about a trio of teens in a futuristic, dystopian world where problematic children can literally be recycled in society by really inhumane means and it basically follows their journey of escaping their unwinding and revolting against the systems put in place. in a way its like the hunger games in regards to themes of revolution

the Gone series is also really good, it's about a large group of teens who become totally isolated from the rest of the world and discover they each have unique abilities and powers, and explores how they rebuild their own society and form coalitions and shit

the Shanara chronicles is another one that had its own TV series but iirc it wasn't very good, I haven't read the books but it's about elves and shit
