“The Skull-Faced Boy” by David Barr Kirtley. I first read this one seven or eight years ago, but it wears well. Two college students die in a car wreck, and as it’s the night of the living dead they don’t stay out of the game for long. Horrible backstabbing and world domination ensue. I don’t think this one’s been made free online, but there’s a link to a podcast version on the right-hand side. I may have to give that a listen.
While looking for the above link: Oh god there’s a sequel! “The Skull-Faced City.” Free and on the internet.
Haven’t read this one yet, but I will in about ten minutes I’ve read it. Be warned! It’s (a) not going to make much sense if you haven’t read the first one, and (b) gruesome in every. single. way. I had a ballpark idea of what to expect from Kirtley and zombies, and I was still stomach-churned. Not safe for sanity, but excellent storytelling and a good undead protagonist. A worthy successor.
