If you mean Shri Keval Muni ji Maharaj, I could verify only a small amount of JainKnowledge information about him, but I could not reliably confirm a complete list of his books from the available Jain source material. JainKnowledge identifies him as a Jain monk and notes his diksha in Vikram Samvat 2005. ( jainknowledge.com)

If you want, I can help identify books written by him, books about him, or pravachan/granth names in a Jain context.
