Give it a Rest, Gail
I feel compelled to mention that How I Live Now was shortlisted (which I think is how the British say "nominated") for The 2005 Orange Award for New Writers. If only I had posted this when it first happened. I was so slow that now I must tell you that the book didn't win. 26a did. The Orange people described How I Live Now as "a novel for all ages."
It has also been shortlisted (nominated) for the Booktrust Teenage Prize 2005. So the book is a novel for all ages, but also for teenagers. Thanks to KidLit for the link.
