18 books in and Venus is the only body this side of Saturn that the Grand Tour hasn’t explored, so it seems a perfectly fitting place to end (I’ll get back to that). There’s something of a continuation of the The Asteroid Wars, with Martin Humphries and his sons as the focus of the books. One (Alex, his clone ) attempted to be the first to reach the surface of Venus and died in the attempt. The other (Van, actually not his biological son at all, but rather the son of his longtime enemy from the Asteroid Wars: Lars Fuchs (I know, right?) ) decides to take on the task of recovering his remains–a pot sweetened by ten billion dollars of his father’s money.
All that actually makes Venus somewhat interesting and unique among the Grand Tour novels. It’s not really one of the corporate war books, such as the early Moonbase books or the Asteroid Wars, but it’s also not a purely scientific exploration of Venus–although there’s plenty of that. It’s really more an an adventure novel with a sci-fi setting and backing in the hellscape that is Venus. That actually makes it a surprisingly solid book.
