Readers' comments ...

Absolutely brilliant – a fine tribute to my grandfather Arthur – it's a wonderful book and the whole family is very proud of it. David Gemmell

I have finally finished the book - been reading it in bits to make it last. It is without a doubt the best book on caving I have ever read, and certainly one of the best adventure books generally.

I read it from cover to cover in a solid twelve hours because I just couldn't put it down.

The rave reviews and comments are – if anything – understatements

Congratulations on bringing out this volume. I'm sure it will be as valued as its predecessor!

Great reading, great photos and great production values. Do buy one!

Thoroughly enjoying this outstanding book. I'm rationing it to nurse me through a series of dull night shifts!

Great book, haven't been able to put it down.

I am really impressed by the quality of the book – its layout, printing, photos, diagrams ... I suspect that the original Underground Adventure and Potholing beneath the Northern Pennines – two of my favourite books over the last forty years – will have to take a step down from the top of the podium to make room for Dave and John's book.

The book is certainly inspirational. A book to savour and which will need several reads, given the vast amount of information in its pages.

An absolutely superb book, the best caving book for a long long time.

Brilliant book, well written and put together.

Rushed through it as I couldn't put it down. One complaint – too short!

A quick glance showed me this is a real classic book on Dales caving. It is well written, illustrated with loads of great photos and diagrams, and produced to an exceptionally high quality. The authors John Cordingley and Dave Haigh are to be congratulated on producing such a splendid book. And much credit to Chris Howes and Judith Calford at Wild Places for all their efforts in making sure the final product is worthy of its contents.

Great reading, great photos and great production values. Do buy one!

I've only dipped in at the moment, but I've read enough to appreciate the quality and the effort, a bloody good read. Perfect copies may become collectors' items, but I'm afraid mine won't be one. It'll become too dog-eared and well read!

What a fantastic piece of work. It has been a pleasure to read such finely written inspiration material. Thank you for writing such a great book.

Have just finished reading Adventures Underground. Really enjoyed it. Another super book for my collection.

I found it a riveting read – the excitement that John and Dave inject into their explorations of the caves really shines through. The tantalising final chapter about the future is fascinating.
