Ah, Tracy as a low income author of non-fiction pop science books a shot in the head feels a bit extreme to deal with my sorrows, but if I could have been in one your named cities a photo would have lovely. I still live in hope of a sales boost but not posthumously.
Back when I had Twitter I used to offer free headshots for low-income authors, not sure I have much reach here but the offer is still there. London or Birmingham (although I’m in Glasgow and Edinburgh at the end of Aug and can fit in a session. Will have lights so can be indoors).
