Interesting story from a writer new to me. It’s a story that will either be (hopefully) continued in Albedo One, or in other publications or novels. Ideally the former so I can find out how the story turns out.
Earth some centuries hence, post-climate change (and a whole lot more) with ‘Cherubs’, perhaps aliens/perhaps not, a man given the ‘gift’ of immortality finds himself increasingly pondering the nature of that gift, in a very strange society. He’s got the tools to defend himself, and the story balances the dramatic action and tension, with some strong imagery, and his philosophical musings.
