Here is my synapsis for a science fiction horror novel. Essentially the story will be set in the distant future where space travel is possible, along with mining on other planets and moons, and colonization on large space stations. One of these stations, Station 13-08, happens to be orbiting the dwarf planet Pluto and picks up a meteorite crashing into its largest moon Charon.
The meteorite exposes an alien structure underneath the creator and everyone gets excited. Multiple expeditions have been operated with more and more of the structure uncovered and documented. Unfortunately, ever since the structure has been exposed, some of the residents at the station have become mentally unwell. This includes insomnia, bad dreams, dementia, schizophrenia, and outbursts of violence. The cause is unknown. Perhaps its the structure itself. Or perhaps it has something to do with various parasitic organisms that seem to infect some of the colonists. What's the connection between the two? These are just a taste of the bigger mysteries at hand.
The story would mainly be told through diary logs given by different personal of Station 13-08. The idea of these logs was that being in deep space can take a toll on one's mental health, so writing a personal diary would help vent out any feelings. The idea came from audio logs and personal texts that are found throughout various science fiction horror video games such as Soma, System Shock, Alien Isolation, and Dead Space. In fact, the settings in those games also serve as the inspiration for this novel. It would have the right amount of horror, ranging from body horror to psychological horror to even cosmic horror.
