The app is all about the text, even if it is beautifully framed by period art and anatomical illustrations. The reader is presented with a screenfull of narration and then offered one or more responses to it. The preferred response, when tapped, pops up another screen of text. (In a visual touch, they appear as sheets of paper fasted together by straight pins.) According to the press materials, the reader’s responses will shape the way the narrative is presented, although not to the degree of substantively changing the plot.
The digital Frankenstein is lovely to look at: beautifully designed and illustrated with old anatomical drawings. According to its makers, Frankenstein "will be the first in a new generation of ebooks, bringing a classic novel to a new audience".
