The latest October 2025 edition with confusingly the same ISBN as the May 2025 version. We are increasingly seeing different editions of books with the same ISBN - This is probably down to economics and short print runs.  However, some conspiratorial booklovers might say this is further proof that we are all living in a dystopian nightmare.

If interested, please inspect contents and sample pages from the download buttons. This edition has 221 pages and extra sections on Thuja and DNA.

Also has better art-type quality paper than the previous version.  Just one copy left of the May 2025 edition. 

ISBN for what it is worth is 97890 83430 164
