With the movie adaptation of Laura Hillenbrand's 'Unbroken' hitting theaters tomorrow, on Christmas day, the nonfiction work showed no signs of slowing down, holding on, once again, to the #1 perch on Apple's iBooks Bestseller list for the week ended December 22. This week 'Gone Girl' rose on the charts slightly, knocking Cheryl Strayed's memoir from the #2 slot it held last week.
