This was my 4th book finished in 2025.

The Celts are something I know basically nothing about, so I was excited to read this book. Sadly after finishing it, I can say I still know essentially nothing about them. I found most of this book quite boring.

This book did a really poor job of even outlining who exactly they were, where they lived and the time frames. It often confusingly mixes up ancient Balkan peoples with more modern people in Wales and Ireland. This is a theme of HH books, whereby so often they don't give dates or locations when they're talking about something. I wish it had been clearer about who it was talking about - specifically I wanted to know about ancient people of Britain; after all this is a British book published in Britain. I appreciate the Celts were once a wide spread culture throughout Europe, but it was rarely clear who was being referred to.

So much of it felt like filler - was it necessary to have 9 whole pages used for a difficult-to-read diary entry on festivals? 

HH clearly got better over time - the ones from the 90s aren't very well written compared to the modern entries released in the 2010/2020s.
