The Solitude of Prime Numbers by Paolo Giordano

This is January Britsnîmes Book Club book. (see : www.britsnimes.com) It's a first published novel. And it's already an international bestseller ! O.k , that's doesn't mean anything as such. But this book is actually good and tells an unusual story with characters larger than life. Here is the plot in a nut shell : friendship over the years between a boy and a girl who stand out and for the outside world are inadequate for "ordinary social life".
I'm sure everybody can somehow identify with all the feelings, experiences very smartly described.
