We each had a classic example of this from our childhood. Charles was after Martin Magnus on Mars, the third in the series, only ever published in hardback, and tough to find. So tough that, before the advent of the web, Charles was seriously wondering if he’d just imagined it! However, he eventually spotted a copy for sale, and pounced.
I got my own copy, a present from my sister who had spotted it lurking in a second hand bookshop in Robin Hood's Bay. And later still, thanks to my review of it on the web, I got a further trilogy.
Wait, I thought. If MMoM is on Kindle, what about A&B? Sure enough, it too can now be had in non-dead tree format.
The times they are a-changin’. But I wouldn’t part with my hardback copy, battered dust jacket and all.
