I have spent at least 8 years writing a book about various things speleological, part memoir, part polemic. It should be published early to mid 2021. I have created a page on my subterranean fishes website that will anounce when it is available. If you are interested go to:

cavefishes.org.uk

find the menu button top right and drop to the bottom menu entry "A series of short passages".

Well done! 

Looking forward to it!

We will definitely buy one for the caving library
