Best new book to me definitely has to be Gideon the Ninth. Lesbians, necromancers, space, the whole shebang. 10/10 would recommend.
Best reread is definitely the Millenium trilogy (The Girl with the Dragon Tattoo, The Girl Who Played with Fire, The Girl Who Kicked the Hornet's Nest). They're all solid books, and I can't read one without diving into the others.
I don't really read comics that much, I should really read more.
