Ray has now turned his hand to writing and in 2019 published the Book of Poems for the Rhino. General Johan Jooste of SANParks was kind enough to write the foreword for the book and referred to Ray as a ''Rhino Whisperer''

All proceeds of the sales of the books have been directed to the Black Mambas, the all- female anti-poaching unit.

In 2020, Ray published a book about the Australian Rhino Project entitled The Crash of Rhinos. The title is a play on words. A ‘’crash’’ is the collective noun for rhinos, but it also describes the carnage wrought by poachers in Africa who have slaughtered more than 10,000 rhinos – three a day - in the past decade to feed the seemingly insatiable demand for rhino horn in some Asian countries. ‘’The Crash of Rhinos’’ traces the origin of the Project to the present situation with the team still working to relocate rhinos to Australia. It is an insightful, frustrating, humorous and humbling story that will make you laugh, cry and tear your hair out in exasperation. In Ray’s own words, “There was extreme joy and there was acute heartache.”

This fascinating story demonstrates what can be achieved by one person with the passion, resilience and dogged persistence to meet challenges, obstacles and the glacial pace of governments - even in the face of a crisis.
