The Egg is only a few pages long, so it's kind of hard to say much about it without super spoiling it, but it kicks off by the reader being told, 'You were on your way home when you died.' What transpires is what happens afterward the reader's death. It's way existential without being up its own bum and raises interesting questions about life, death, reincarnation and religion in an accessible way.
Really quick read by a talented author. Definitely recommend it for your lunch break.
