I want to know the answer to the following question:
Who wrote 'The World In Grey'?
All the background I'm provided with is that "Published in 2008, The World In Grey: Dom Bosco's Prophecy, by author Ryan J. Lucero, tells an apocalypticle story based on the famous prophecy from the late 19th century by the Italian saint Don Bosco.". Is that enough to answer the question?
Answer: yes
