The Solitude of Prime Numbers

“The Solitude of Prime Numbers” was a pick from my book club, which I wasn’t expecting to like, though actually I didn’t know anything about. But like a moth to a flame I was completely drawn in by this sad, moving novel from 2008. Chalk it up to author Paolo Giordano’s talented storytelling, which captured my imagination and made me follow these damaged characters with such interest.

It’s a love tale of sorts between two lonely outcasts who are both haunted by childhood tragedies. The girl, Alice, lives with a crippled leg from a ski accident and a bullying father. The gifted boy, Mattia, carries the guilt of abandoning his mentally challenged twin sister who disappears and is never found. Alice and Mattia meet in high school, where they sense in each other a kindred spirit of inner pain. He deals with it by cutting himself, she by being anorexic.

To Mattia, who later becomes a mathematician, he and Alice are like twin prime numbers, “alone and lost, close but not close enough to really touch each other.” They separate when he accepts a research job in another country and she marries a local doctor, leaving issues between them unresolved. But many years later they resurface when their paths cross again.

The ending that follows is a bit inevitable but a surprise all the same. The novel leaves quite an impact long after it is over. I found it a quick read with an underlying suspensefulness that made me keep turning the pages. Its often beautiful passages and clever use of math metaphors are quite transcendent.

I was lucky to come across the author (an Italian physicist) in 2010 at a book festival where he read aloud the chapter in which the twin sister goes missing. I remember it being quite disturbing and yet visual. I thought what is this? And now I know. “The Solitude of Prime Numbers” is a small tour de force on the weight of childhood trauma, love, and loneliness. Apparently it was made into a movie in Italy in September 2010.
