This story was based on such an intriguing and original premise and given how difficult it is to be truly original in the sci-fi genre, that's impressive. But I did wonder at the advantage for the aliens, of accessing the Galactic Library through a human interface over, say, a computer one.
Putting that one question behind me, however, I loved the characterisation of Matt and the slow reveal of his motivations and I loved this fascinating world and would very much like to learn more about it.
I have to say the narrator added so much to my listening pleasure, too.
Thanks!
