A few books by Russian historians on Prokorovka have been translated into English recently - I can recommend Demolishing the Myth: The Tank Battle at Prokhorovka by Valeriy Zamulin. It's been a while since I read it, but he doesn't seem like he's out to make the Red Army look particularly good. I particularly remember him ripping Rotmistrov to shreds. There are a lot of first hand accounts from soldiers in the field from both sides, which he compares to official reports and documents.
It isn't really pop history, so it is extremely dry in places, but it is well worth a read if you are interested in Kursk.
