We listened to this on audiobook on a recent family road trip. It was only my second time with Sorcerer's Stone, but my daughter had recently read it on her own (twice) and had her father read it to her once and even after all of this, she was still engrossed in the audiobook. 
 It's not my favorite of the books (thankfully, unlike so many series for kids, this is one that got noticeably better as the series progressed), but it helped get us through a 2.5-hour wait at the border crossing at Niagara Falls. Who knew that so many U.S. citizens would be trying to get into Canada on the 4th of July?
