As anticipation continues to mount for the Valentine’s Day release of the Fifty Shades of Grey film adaptation, the book hit #1 on Apple’s iBooks bestseller list. The first book in E.L. James’s trilogy sent last week’s top seller, Paula Hawkins’s blockbuster debut thriller, The Girl on the Train, to the #2 spot.

A week after word broke that Harper Lee would be releasing a second novel, more than half-a-century after To Kill a Mockingbird was first published in 1960, Mockingbird anded at #3 on Apple’s list.
