How to Decide?

I'm on the home stretch of the first draft of my new novel. Once that's done I shall set the manuscript - silly word since it's gone straight onto my PC - aside for some weeks and read someone else's fiction. And grind my teeth because they are achieving what I cannot.

But what? I'm most tempted by Amitav Ghosh's second part of his Opium Wars trilogy, the first having been spectacular.
Anyone suggest anything else?
