" The reason I picked up this book was due to the title. I love prime numbers. I love teaching math and the whole idea behind this book is a math concept. These two people are very different, unique on their own, and are equated to prime numbers. Running through their lives in contrasting pains. There is a subconscious line between them. The writing was very good. I could tell this book was written by a guy or really from a guy's perspective, though it looks at the world through a male and a female character's eyes. There was such compartmentalized viewpoints and fractions of moments not going beyond yourself to finally connect with another human being. The book is a fast read, but left me a little perturbed by the ending. I felt spent from finding out what really makes one a prime number. "
