Here is the goodread's story line of Under the Skin:
Isserley picks up hitchhikers with big muscles. She, herself, is tiny-like a kid peering up over the steering wheel. She has a remarkable face and wears the thickest corrective lenses anyone has ever seen. Her posture is suggestive of some spinal problem. Her breasts are perfect; perhaps implants. She is strangely erotic yet somehow grotesque, vulnerable yet threatening. Her hitchhikers are a mixed bunch of men-trailer trash and travelling post grads, thugs and philosophers. But Isserley is only interested in whether they have families and whether they have muscles. Then, it's only a question of how long she can endure her pain--physical and spiritual--and their conversation.
Michel Faber's work has been described as a combination of Roald Dahl and Franz Kafka, as Somerset Maugham shacking up with Ian McEwan. At once humane and horrifying, Under the Skin takes us on a heart-thumping ride through dangerous territory - our own moral instincts and the boundaries of compassion.
