I. E. M.
There doesn’t seem to be a clearly identifiable author writing under the name “I. E. M.” in the reliable sources I found. The initials most often point to a music project, not a book author, so I’ve kept this entry cautious rather than guessing.

About the author
I wasn’t able to confirm a solid literary profile for I. E. M. from reliable web sources.
Search results for these initials mostly point to Incredible Expanding Mindfuck (I.E.M.), a music project by Steven Wilson, rather than to an author. I also checked broader references for writers who publish under initials, but I couldn’t verify a matching author entry for I. E. M..
If you meant a specific writer who uses these initials, a book title or full name would help narrow it down and make the profile more accurate.
