Peter Cameron - and books with teenagers in them

Frank Cottrell Boyce, in his glowing review for Patrick Ness's The Knife of Never Letting Go, bewails that such fiction needs to be targeted at a narrow demographic, 'young adults', as though teenagers need their books sorting out for them in case they wander into grown-up territory. Catcher in the Rye, he points out, would be tucked away on a 13+ shelf nowadays.
I've taken his lead, and ordered Patrick Ness's new book for my own enjoyment. And I also happen to have just read another book about a teenager that any adult too should delight in. I've loved Peter Cameron's work since first reading his 1997 novel Andorra. His prose in itself is a lucid joy - see how it strikes you with this download of the book's first chapter. The narrator of Some Day this Pain will be Useful to you has little success in making friends in his own life, but I'm very pleased to have come to know him. I laughed numerous times, gently but aloud.
