Feed
Mira Grant is the pseudonym Seanan McGuire uses for her horror books.
Feed is the first of a trilogy set in a post zombie uprising world.
Georgia and Shaun Mason are news bloggers who get the nod to cover a presidential campaign and find themselves caught up in conspiracy and murder.
Feed has great characters, excellent worldbuilding and I got genuinely invested what happens as the story unfolds.
Another compelling book by this author and I highly recommended it if you have any stomach for zombies and horror.
