I went to Amazon and read the first line of Feed, I could see this was going to be tongue in cheek . . . um . . . well, you get what I mean.
Note: Mira Grant is the author of the Newsflesh Trilogy and she is also Seanan McGuire who writes the Toby Daye books.
And I then totally realized that I promised you zombies. .. well not zombies exactly but a write up of the Newsflesh trilogy. These things are connected: Seanan McGuire and Mira Grant are the same person.
And as such: the newsflesh trilogy is quite as much fun to read asher Toby Daye books.
How to describe them: they are series of political/medical thrillers disguised as zombie novels. The characters are vivid and so is the writing. The books are fast paced and very enjoyable. I think that they are by far the most enjoyable zombie books I've read. (And I have tried quite a few - there are quite a few out there now!)
