Agreed, an impeccable line up!
Great to see The Secret Life of the Periodic Table in @foylesforbooks.bsky.social Charring Cross Road. There is a signed copy on the shelf if you are thinking of getting a copy.
On a walkabout after dinner last night I dropped into @waterstones.bsky.social Piccadilly and signed a copy of The Secret Life of the Periodic Table. If you're in London and want a signed copy head there to the 4th floor where it can be found in the Chemistry books section.
Giving an author talk at my local community library on the re-release of The Secret Life of the Periodic Table @hachetteuk.bsky.social Northfields Community Library, 7:30pm Thursday 14 August
A great review of The Secret Life of the Periodic Table in the @waterstones.bsky.social website www.waterstones.com/books/review...
"The author tells the story of the people and places around each element... a compelling story of human curiosity..." #book #science #chemistry
