Since you can imagine, why not imagine more? But, how do you know that I am imagining it? If the book is documentary, will you have any questions about the world you live in?
Tomb robbing + immortality + time travel + supernatural + interstellar + suspense + underworld + any theme you can imagine.
I'll be responsible for writing, and you'll be happy and that's it.
Watching a group of psychopaths go to the universe to provoke an interstellar war, propel me to the throne of the strongest king in the universe!
