"Mesmerizing...an exquisite rendering of what one might call feels at the subatomic level." -The New York Times A prime number is a lonely thing. It can only be divided by itself or by one, and it never truly fits with another. Alice and Mattia are both "primes"-misfits haunted by early tragedies. When the two meet as teenagers, they recognize in each other a kindred, damaged spirit. Years later, a chance encounter reunites them and forces a lifetime of concealed emotion to the surface. But can two prime numbers ever find a way to be together? A brilliantly conceived and elegantly written debut novel, The Solitude of Prime Numbersis a stunning meditation on loneliness, love, and what it means to be human.
