Walking to Aldebaran

This was pretty much designed to hit all my buttons - a horror/SF mash up, with a giant mysterious and ancient alien artifact at its core? Oh yes please. It's not hard to extract strands of it's DNA - think Rendezvous With Rama, Cube, Diamond Dogs (Alastair Reynolds, not David Bowie), Alien, Rogue Moon - but then again, some of those works are my very favourites, and this can stand with them. Fats paced and just the right length, this is one to enjoy and then to savour on rereading.
