Unfortunately, Amazon, Apple and Barnes & Noble have not shared their readership data. Kobo didn’t share overall completion data for other genres. The completion rate for books in the mystery genre is 62%.The most completed book in the UK in 2014 was the self-published thriller/crime drama Rotten to the Core by Casey Kelleher with an 83% completion rate according to Kobo.According to Kobo thrillers and romance novels have the highest completion rates in general. Being a best-seller didn’t necessarily correlate with being a book that was finished.end of books found that Nobel Prize winner Daniel Kahneman’s Thinking Fast and Slow was only finished 7% of the time and much lauded and discussed Capital in the 21st Century by Thomas Pickety was finished less than 3% of the time. Jordan Ellenberg, a mathematician, by comparing highlighted passages in beginning vs.Twelve Years a Slave by Solomon Northrup was finished 28% of the time in 2014 (this book, written in 1853 was widely bought in 2014 due to the movie being released) – data also from Kobo.According to the e-book firm Kobo The Goldfinch by Donna Tartt was the 37th best selling book of 2014 and won the Pulitzer Prize but was only finished by 44% of those who started the book.Of particular interest is how often we finish books. Data is being mined about how much of various books we read, how long it took us to read them, how often we picked them up vs. When we read on an e-reader many details are known to Amazon/BN/Kobo/Apple about who exactly is buying the book and our behavior with the book. Within a minute a got an email from Goodreads asking me how I liked the book I just finished and suggested others I might like (btw – it was great book called “ The Emerald Mile” by Kevin Fedarko – I’d highly recommend it). A few days ago I finished a book on my Kindle app for iPad. Data about our lives is being collected in ways we may have never before imagined.
