The third book of the Red Rising trilogy by Pierce Brown. The second book was arguably my favorite ever work of fiction.
They’re a mixture of Star Wars, Game of Thrones and the Hunger Games.
I’d highly recommend them to anyone. Although they’re incredibly violent books.
Dune - the sci fi fantasy books that they’ve started making films about.
I wasn’t too keen on the first film, although that was in part because of it being a Part 1, but the books are brilliantly written and thoroughly engaging.
