I loved this book. My copy is well worn from reading it twice and lending it to many others. And also from shipping it to England.
I sent this to Mark Haddon's agent with a SASE and didn't really expect to get it back. I reasoned I could always pick up another copy somewhere else.
To my surprise, not only did he sign it, he drew a little dead dog inside. This was AWESOME! I love that he did this. I've read all his books and seen the movies.
