I'm sure there's space out there (puns not intended) for a Kim Stanley Robinson-esque epic/series about the colonisation of Venus, but for now I must say that Bova has slotted together a quite impressive story-driven narrative with this book. It's a *tale*, as opposed to a piece of techno- or sociologically-centred literature, as KSR might write.
Quite unlike his two "Mars" books, the tale is one of unremitting corruption, greed, violence, and death, these facets almost unsettling in their explicit profuseness. The hero is a weakling, whose main character advancement is to prove himself otherwise to a ship-full of brash, macho survivors he finds himself marooned with, when he is rescued from the death of his own ship high in Venus' cloud-tops. The gore and sex-soaked contents are almost-but-not-quite sickening, and anyway manage to portray enough of a moral message to excuse them. The central conceit swinging around hatred, rejection and family loyalties is exceedingly well done. And there's a twist towards the close which, although well-executed, is distinctly lifted from a well-known film I could name...
The make-up of the book seems to encapsulate the planet: hellishly gripping, morally corrosive, thick and murky and unremittingly hostile, turning up the heat the deeper down you go. Soaked in familial loathing, death and greed. Which of course gives it a certain appeal. And the ending is thoroughly bittersweet. Bravo!
A nearly unrecognised masterpiece, in my opinion, like so much other hard SF. Four point five stars.
