Default I need a recommendation for a book cover

Hey guys! I got tired of my actual TPU case (exactly like this one), and now I want to replace it. Can you guys suggest me some good book covers/flip covers (I think there's no difference between them, but whatever)? If possible, I would like those which has magnets, and possibly the sleep/wake feature.
