Im looking for a zombie book series

I can't remember the name for the life of me, but it's a series following a male lead where sometimes when bitten by a zombie, you get some sort of super power. The only detail that I really remember beyond that is that it takes place loosely in our world and there's a guy who got impenetrable skin after being bit that had a taste for celebs that became zombies (icky).

The series was very interesting, and I remember it not being finished when I stopped reading it. Please help!
