This book cover and title attracted my attention. It’s a definite entry in my top book cover awards competition, for typographical treatment, a fresh nearly-naive design, and for the illustration.
The “two peas in a pod” image conveys a cozy togetherness that belies the (absolute) solitude implied in the title. In one fell blow, the designer has conveyed the premise of the book: that the plot revolves around two characters drawn together by their shared loneliness.
The overleaf:
A prime number is a lonely thing. It can be divided only by itself or by one: it never truly fits with another. Alic and Mattia are both “primes”—misfits who seem destined to be alone…When the two meet as teenagers, they recognize in each other a kindred, damaged spirit.


I got this book the other week from my library during a hardback sell-off to make space for 10pence! But the cover is totally different – and I much prefer this one with its host of subtle meanings behind the simple design. A prime number can only be divided by itself or one so 2 is the first in an infinite series which never ends and when they do sit with each other, interesting things happen – like in this book. It is in fact a great read.
