So the first volume of "The Fall of the Sea People" is on Kindle.
I am working on a genuine squashed-trees edition, possibly for sale from my own website. It should also be available through normal book distribution channels, but the advantage of buying it from the website would be that I could autograph it before shipping it.
The disadvantage would be that I would have to post it from Ireland: possibly adding €5 or so to the cover price (€12.99 in shops, so maybe €18 or so in total.)
If you think you would be interested in a squashed-trees edition, signed by my fair hand, please add a comment to let me know.
