This question is lifted from author Sahar Sabati's informative Ask an Author series, which ran from 2015-2016 and included responses and reflections from English-speaking authors from around the globe. Since I'm often asked these questions by readers, I have republished my answers here with Sahar's kind permission.
How many books? How many books? I have so many print books, we’ve had to rent a storage unit to store them, which is a bit silly because while they’re boxed up in cartons, no one is reading them. The space problem has become so dire that I have now made it a policy only to keep print books which have been signed by the author—a necessary decision, if there is to be any room left in the house for us. As far as the book I have read the most, I’d like to cite a literary classic like To Kill a Mockingbird by Harper Lee or Peter Pan by J.M. Barrie, but the reality is children’s titles like Rosemary Wells’ Max and the Chocolate Chicken, Grandpa’s Slippers by Joy Watson and Tales of Amanda Pig by Jean van Leeuwen are the most read and dearly loved tomes of all time in the Murray household.
