Mac's Book Club meets to discuss The Solitude of Prime Numbers by Paolo Giordano. 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 Numbers is a stunning meditation on loneliness, love, and what it means to be human. "What a shock to open a novel written by a young physicist in Italy and find myself there, on every page. No wonder Giordano's readers can be counted in the millions; this astute, aching contemplation of solitude has a power to make us all feel a little less alone. A love story told with astonishing perceptiveness and remarkable subtlety, The Solitude of Prime Numbers is an extraordinary affirmation of the reasons we read." -Stefan Merrill Block, author of The Story of Forgetting
