If you're attending the Cymera SF festival in Edinburgh next weekend (May 31st to 2nd June), among other things there's a charity auction to raise funds for the Scottish Book Trust's New Writers Award, along other things.
I've just donated a signed first edition hardback run of the entire Merchant Princes/Empire Games series, published from 2003-2022 and occupying roughly 30cm of shelf space! Hopefully someone will bid on it and help fund the writers award ...
