As you may know, I'm all for coming up with innovative ways to get attention for your writing, but it may be that Michelle Paver went one step too far. She was signing copies of her book, Soul Eater, which features a wolf talking to a child, so she brought with her...two young wolves.
These two turned out not to be as well-behaved as one might expect for a quiet Waterstone's branch...they leaped on chairs and windowsills, ate some books, and relieved themselves on the carpets.
Maybe the old actors' warning about never working with children or animals applies to book signings, too...
