We haven't been successful at making direct contact with Mike. We had hoped to discuss possible options for making the descriptions available now that the book is out of print, or supporting a reprint or even an update (as many of the caves have now been CNCC anchored).
However we understand Mike has been made aware of the demand for the book any may be exploring reprint options, but nothing concrete on that yet.
So, nothing to report so far, but we wouldn't be rushing to pay £1000 for a copy on eBay just yet!
Just for a bit of fun... if the book were to be updated (this is hypothetically only) which trips would you now add?
Which would you remove?
