The Solitude of Prime Numbers(2008)  is the sort of book that some of us find hard to ignore. A winner of Italy’s prestigious Strega Prize, a 27 year old particle physicist/author, a come hither title and a mathematical concept used to describe the relationship between two lonely souls:

Prime numbers are divisible only by 1 and by themselves. They stand in their place in the infinite series of natural numbers, squashed in between two others, liked all other numbers, but a step further on than the rest. They are suspicious and solitary… … among prime numbers there are some that are even more special. Mathematicians call them twin primes: they are pairs of prime number that are close to one another, almost neighbors, but between them there is always an even number that prevents them from really touching.

The story is told in chronological order of ascending years with varying intervals. Nine year old Alice, in the opening chapter of the book, endures a horrific ski accident that leaves a permanent injury. Mattia, of similar age, decides to leave his mentally disabled twin sister, Michela, in a park while he attends a party. Michela subsequently disappears. The consequences of these two incidents on the emotional and social development of Alice and Mattia, as they mature into adults, are far-reaching and devastating. The teenage Mattia is very withdrawn and isolate himself socially, preferring to immerse himself in mathematics. He is a curious figure to his peers; some are even drawn to his sad, unreachable persona. Mattia self-mutilates by cutting. Alice is more accessible than Mattia; but she suffers from extreme anorexia and self-loathing. The two end up at the same high school and the first half of the book describes the growing relationship between these twin primes. Giordano’s handling of Mattia and Alice during their teenage years is quite masterful. He quite successfully, with a sparse, yet poetic, narrative fleshes out two very tormented young people, who are emotionally frozen in relation to the people around them but are more fluid with each other. Mattia and Alice, by the end of their teenage years, are able to fashion out a way of relating to each other within the tortured confines of their psyches.

Unlike the first half, the second half of the book was wholly unsatisfying. As adults, Mattia and Alice, repeat the same patterns of behavior. The story reads as a variation of their teenage years, even as he leaves to take up a post in another country and she gets a job and marries a doctor. Having created characters with such depth, Giordano fails to take advantage and exploit these characters, choosing instead to deal with them superficially. There are no insights, no movement in them as adults. They are quite literally stuck. Consequently, I lost interest in the novel’s continuing exploration of the relationship between the two characters. Instead, I thought something should have been said about Mattia and his emotional and mental awareness of his disappeared twin. The figure of Michela hovered in the novel and I was intrigued when Mattia says to Alice:

She was identical to me. Completely identical to me.

But this goes nowhere. Towards the end, Michela is dragged into the story as a ploy to justify the return of Mattia to Alice. Surely, Alice could have written “The roast is in the oven. Come get some” and Mattia would have hopped on the next plane. Mattia’s reaction to Alice’s summoning and his subsequent inaction makes sense within the context of their friendship; the nature and the limits of which were established and set by the end of the first sections of the book. In short, I don’t think I would have missed much if I chose not to read the last hundred or so pages of the book.

My rant against the second part aside, The Solitude of Prime Numbers is a well-written book. It is quite evident that Paolo Giordano has considerable talent. His prose is graceful and there are passages in the book that are just superb. There is an aura of melancholy and loss, in step with the story, which I loved. The translation by Shaun Whiteside must be perfect because the book reads so well. It is quite an achievement for a debut. But, and as I divined, I did not love it.
