Penny, a graphic novel by Karl Stephens, is the whimsical story of the inner life of a humble tortoiseshell cat. Like many cats, she started life as a stray and was taken in (or kidnapped as she sees it) by two humans. Now that she has secure food and shelter, she spends her days contemplating various philosophical questions such as "Is time elastic?" and "What is the point of trying when the world is bent on destroying you?" She is often aided by catnip, in a sort of feline vision quest. Penny is not just an armchair philosopher as she does at one point leave her brownstone to have a small adventure. Penny is a graphic novel for both seekers of knowledge and lovers of cats.
