This likely makes more sense if you remember that Warm Bodies, the 2013 film starring Nicholas Hoult and Teresa Palmer, is based on a book by Issac Marion. Marion has announced The Burning World will be released in 2017, continuing the tale of R the zombie's and Julie the living girl's star-crossed (flesh-crossed?) romance. Here's the synopsis from Marion's website:
R is recovering from death.
He's learning how to breathe, how to speak, how to be human, one clumsy step at a time. He doesn't remember his old life and he doesn't want to. He's building a new one with Julie.
But his old life remembers him. The plague has another host far more dangerous than the Dead. It's coming to return the world to the good old days of stability and control and the strong eating the weak, and stopping it will require a frightening journey into the surreal wastelands of America -- and the shadowy basement of R's mind.
And here's the cover:
The Burning World is set to be released 7 February 2017. If you pre-order it from Marion's website, you'll get a pdf of "post-apocalyptic America's last newspaper, the Exed World Almanac, a bizarre but enlightening 'zine' hand-drawn by a mysterious character who you'll meet in The Burning World". Unfortunately, pre-orders aren't yet available in Australia, but there's also a short excerpt from the novel, if you're so inclined.
