The Italian Novel

Italian astronomer Paolo Donati makes two troubling discoveries in November of 2032-his lover is seeing someone named M at the Biblioteca Nazionale and there is another Earth-sized planet orbiting the sun. Before he can plot his next move, he and his research assistant Rosa are dragooned by shadowy state operators and complications ensue. The story ends in Paris, where Paolo tries to figure out what love might mean as Planet X closes in.
