True to the webpages uncovered earlier in the week, Amazon has unveiled a new e-book subscription service. Dubbed Kindle Unlimited, the service gives access to both e-books and audiobooks, though with restrictions on the latter. Kindle Unlimited is priced at $9.99 per month with a 30-day free trial, and it allows users to read any number of the 600,000 available titles. By saying audiobooks are available, Amazon means that “thousands of Kindle books come with the free professionally narrated Audible audiobook.” Kindle Unlimited subscribers also get three months of an Audible membership (normally $14.95 per month), which translates to three free audiobooks. There are no standalone audiobooks available through the service.
