Rich Horton posts his review of Alan Dean Foster's Sagramanda, apparenlty orphaned from Locus magazine, over on CoolSciFi.com. He makes the inevitable comparison with River of Gods, though is fair in pointing out it really is apples to oranges in terms of authorial intent and scope, but seems to like Sagramanda none the less:
"Foster's novel is not so brilliant as McDonald's, and really it makes no attempt to be brilliant at that level. Rather, it is an enjoyable and fast-moving thriller - and quite successful as such.... It's quite an exciting read. The plot moves sharply, and quite believably... The portrait of fairly near-future India is fairly well-done, though here the book truly does suffer by comparison with McDonald's altogether more complex and deeper portrait. Sagramanda is no masterpiece, but it is fun and not without deeper shadings."
I would add only that both McDonald and Foster were plugging into the zeitgeist at the same time and have produced two very different works, both valuable and enjoyable in their own rights and for their own reasons. Where McDonald's work is sort of a futuristic Kim, Foster's is a technothriller enhanced by the experience of a nonWestern setting. Obviously, I enjoyed both enormously, but then, I would. I think you will too though.
