After reading Reverend Insanity my heart is very empty. I can't just enjoy any random book anymore like everything feels lacking and soulless. Reverend Insanity is one of the very few novels out there that one can truly enjoy with their heart's content! For all my fellow authors and readers alike, do read out RI at least one time, I guarantee you wouldn't regret it. You'll surely get some truly wonderful insights for your own story as well.
And yes there is very rich content in it so I wouldn't really recommend it to anyone below the age of 16.
