This is the follow up to Warm Bodies. R and Julie are still together and R is living in the human compound, trying to become more human, with mixed results. M aka Marcus has wondered off to the woods to find himself.
Lots of zombies have moved into the human zone, as they make the slow transition from dead to barely alive to living. But someone has figured out that zombies can be trained to do simple tasks and has created zombie factories. And this group has decided it is going to run everything and is moving in on all the human enclaves and setting themselves up as the final authority. Anyone who resists is in danger as is anyone who tries to stop them from rounding up the zombies and the semi-zombies.
R and Julie run afoul of this corporate takeover of their compound and are forced to escape. In the process, they encounter Julie's dead boyfriend's brother and find out he is a pilot.
Pursued by the goons of the corporation, they return to the airport and take off in R's old home, the airplane. But their escape is only temporary and R is starting to remember some very disturbing things about his past and his strange connection to the corporation.
The first book was kind of cute and charming. This book is the opposite. It is grim and depressing and obviously the next in a series. It's an interesting story, but too dark in tone for my taste.
