(A much shorter review than usual, since I have broken my left elbow and am typing with one hand in a cast.)
Not a particularly original story or even mash-up of tropes. Walking to Aldebaran piggy-backs on that time-honoured sub-genre of Big Dumb Object stories. Lots of cool ideas and set pieces from Adrian Tchaikovsky, but very little that is surprising or truly interesting above and beyond the skill of the writing style itself. Thanks…
