We all imagine things. The trick is to know when you're doing it, anyway most of the time. The Hoboken Chicken Emergency is the name of the book, but the same chicken and Hoboken appear in Looking for Bobowicz and The Artsy Smartsy Club, which are different books. If you look at the title page of any of my books you will find small print which says I am not responsible for readers becoming confused.
