Lostjem Stories

It's about this vampire prince and this girl she might have been kidnapped I don't remember but there mates so everything is ok-ish. In an apocalypse time where they could not go out side with out an air filter unless they will be turn to a zombie. There are zombie attacks, while there enjoying life and the girl gets bit by one and now she continued detect when an attack is coming. That's so far of where I have gotten to the story that I remember. It's really long but such a good book made in probably 2012 maybe earlier. If you have a story like that or know the story please message me. Thanks for helping in this search.
