Review Detail of Xreth in The Stone at the End of the Universe

I've done quite a bit of research for this so I'm gonna use that as my basis for my self rating of 5 hehehe. Thank you for the support so far but the novel has only just started. Please expect more unique stories about the last living civilization in the known universe and the other civilizations in other universes. The actual genre for this is Sci-Fa (Science Fantasy) but there was no option when i had to select so since the story starts with scifi, I placed it there.
