I read almost exclusively fantasy and sci fi. Here’s a few favourites.
Sci fi: Red Rising Trilogy Bobiverse The Martian and Project Hail Mary
Fantasy: The First Law Trilogy (my absolute favourite of everything I’ve read) Brandon Sanderson (literally any of his stuff. If you’re looking for a trilogy, start with Mistborn and if a stand alone, Warbreaker). Don’t be overwhelmed by his Cosmere world, if you only read mistborn era 1 it wraps up in a nice bow. Robin Hobbs first trilogy is a nice introduction to her series. If you don’t love it it wraps up nicely after the first trilogy.
Dystopian: Unwound by Neal Schusterman Arc of the Scythe by Neal Schusterman
