John Ajvide Lindqvist is the author of the novel Let The Right One In, which is a lot more popular so if you looked at that name like "I feel like I know that name..." that might be why. Let The Right One In is a love story mixed with a thriller that involves vampires. It's really good - so good it inspired 2 live action movies.
Handling the Undead is a story about grief and the trauma of losing a loved one that happens to have the walking dead in it. I say the walking dead because they're not zombie - they don't attack people and the phenomenon is not worldwide. It isn't even country wide in this novel!
Set in a small city, a little under a thousand bodies within a narrow time frame wake up. They aren't alive but they're walking around and that obviously causes some Concerns. The novel touches upon the political and social issues that come with such a thing happening - we get depictions of how hospitals are handling it, how the government responds, how emergency personal react, and then also how our individual POV characters handle their dead walking around.
It was a fairly quick read once I actually got the time to sit down and go through it and by the end I might have had to sit for a bit and cry a little. It was a really good book, y'all.
