The Solitude of Prime Numbers

תקציר:
A Prime number is a solitary thing: it can only be divided by itself, or by one; it never truly fits with another. Alice and Mattia are also alone with their personal tragedies. as a child Alice's overbearing father drove her first to a skiing accident, and then to anorexia. When she meets Mattia she recognizes a kindred spirit, and Mattia revels to Alice his terrible secret: that as a boy he abandoned his mentally-disabled twin sister in park to go to a party, and when he returned, she was nowhere to be found. As they grow into adulthood their destinies seem irrevocably interwined. But then a chance sighting of a woman who could be Mattia's sister forces a lifetime of secret emotion to the surface. -- מן המעטפת האחורית
