Recommended for 13 and older. Minimal sexual content, but there is violent and adult content.
Because it is a very short story it is hard to do a review without giving too much away. While very reminiscent of Tell-Tale Heart by Edgar Allan Poe at a point, this is a deep space story that has a good build up and even leaves you with a good ending that I admit that I had to re-read twice to make sure I wasn't just jumping to conclusions because I'm a nurse.
FYI, this is short enough, and just enough build up, and realism, that I would even consider it for a campfire story to scare other teens and adults. After all, those are the scariest stories of them all.
