Prof. R.G. Strom: "You have really written a great book. I hope it sells a million copies. There is mounting evidence that the Moon is still active, so you were right all along".Maurice Collins: " I am thoroughly enjoying Secrets of the Moon. It is one of the best lunar books that I have read in a long time. It has opened my eyes to the possibilities of there being more volcanic processes at work on the Moon than I was aware of before. I especially liked the section on the origins of small craters and was impressed by the close resemblance of the Elegante crater in Mexico to a lunar crater. Elegante looks more lunar than Meteor Crater. Secrets of the Moon will be an essential volume in my lunar book collection. Also, your book has gotten a lot of likes on Social Media: 27 so far on my Facebook page and 13 more on a Facebook lunar group called "Maurice Collins: "I'll re-read Secrets of the Moon as (there is) a lot to absorb, but I found it a very good survey of the Moon and it shows that there is still research to be done and has given me things to think about. It was good to have a brand new book out on the subject".Prof. H. Pinkerton: "Congratulations on completing your splendid book. It has come at the right time, given the interest in developing manned stations there, and your insights will, I am sure, be welcomed by those in charge of such exciting projects"Dr. Thorsteinn Saemundsson: " Secrets of the Moon is a new and ambitious piece of work with a catching title and I am impressed. We must hope that this book gets the attention it deserves and that the currently accepted view of the Moon's features will be revised".Prof. James Head: "Secrets of the Moon (includes) lots of good ideas..."Dr. R.J. Fryer: "I feel that your latest book, Secrets of the Moon, is a useful, comprehensive and good summary of a lifetime's work. Hopefully, it will have the effect that it deserves whilst the new lunar interest, due to the multinational landings and future plans, persists. I enjoyed reading it."Owen Edwards: "I think that Secrets of the Moon is a very impressive feat!"
