My best friend often teasingly tells me that the books I recommend to her are all too depressing and sad. I always counter that I recommend books that make me laugh. Now, that either means that I have a sick sense of humor, or it simply illustrates that the stories I most enjoy reading combine painful topics and awkward characters with humor, sarcasm, and witty writing.
Paolo Giordano’s The Solitude of Prime Numbers is exactly such a book.
