No.  The service is the summaries and you can buy and listen to full audiobooks in the app.  They aren't free but the button is there.   The content you get from Blinkist are blinks—meaning they are summarised versions of the complete book. Designed to be finished in 15 minutes or less, these blinks are carefully handpicked and written by expert writers to make sure readers are treated with all that a book has to offer, minus the hassle of reading it end to end.
