Yesterday I finished Feed by Mira Grant.

Feed is a post-zombie apocalypse type book, but one where civilization didn't fall.  It's set a number of years after a rogue genetically engineered virus starting converting people to zombie, where people have adjusted and go on with life.  Civilization works fine but has added many new constraints to deal with the possibility of continued outbreaks.

The protagonists are journalists (i.e. bloggers), a brother/sister pair and one of their friends, who get invited to cover a presidential contended and then get into trouble.

A strong read - more thought out than most similar books, with some surprising twists and turns along the way. 

Mira Grant is a pen-name for Seanan McGuire, who also writes urban fantasy under her own name.  I enjoyed Feed more than Rosemary and Rue,  since it did more to extend and surpass its genre.  I'll still probably check out the sequels to both books.
