In most types of books where amnesia is used as a device, the pursuit of idnetity usually drives the plot. In this case, however, Ferrell plays another game entirely. He uses this blank canvas status and lack of personal history to turn his character into a metaphor, exposing society's voracious appetite for fame. Numb's unique relationship to pain becomes his brand and a mirror which reflects some of the hidden twists and kinks of celibrity - particularly how it impacts on friendship and relationships.
I'm not sure I liked any of the characters. Mal, perhaps. There is a very authentic feel to him, although it would have sucked to be his friend. Yet the book makes a compelling read. Recommended, if you can stomach all that random bloodletting.
