The Overturn ability Miserea neither "destroy" or "return any cards to hand", so Emma cannot prevent that. And Miserea will nullify your own cards' abilities so you cannot use Soulguard to protect the book. However, it's a different case if your flag is currently Lost World as main deck cards cannot be put into Lost Deck so your book and all main deck cards will just stay while other Lost World cards will  be shuffled back into the deck, and you draw and charge gauge like normally. That's why Folktale players tech Overturn Miserea for Lost build as it means free 6 draws,

"cannot be destroyed, cannot be returned to hand, and souls cannot be dropped" are tied together with "by your opponent's card effects"
