AN APOCALYPSE OF OUR OWN by Jeff Strand is the story of two friends stuck in a bomb shelter together for months. Eventually they become friends with benefits, but that is a minor detail. Missy and Kevin are awesome characters, and I think this story would work as a horror-comedy movie.
I'm not certain the author meant to be funny, but I laughed out loud more than once. Despite the dark humor, this novella still has its terrifying moments. The setting is absolutely claustrophobic, and the tiny bunker alone is a frightening concept.
The apocalypse isn't explained until the very end, but the reason is very satisfying and a tad bit ironic. This is definitely one of my favorite Strand stories!
