• By   • Alexandra Alter  Kobo, which makes digital reading
devices and operates an e-reading service that stocks 2.5
million books and has more than 8 million users, has recently
started looking at how readers as a whole engage with particular
books and genres. The company tracks how many hours readers
spend on particular titles and how far they get.  Kobo recently
found, for example, that most readers who started George R.R.
Martin’s fantasy novel “A Dance With Dragons” finished the book,
and spent an average of 20 hours reading it, a relatively fast
read for a 1,040-page novel. Readers tore through “Mockingjay,”
the 400-page final book of Suzanne Collins’s dystopian trilogy,
finishing in just over seven hours. Kobo also found, comparing
fiction and nonfiction titles, that readers tend to spend longer
chunks of time reading novels than humor or diet books.  Take a
look at this chart on average reading prices and reading times
(in hours).
