Hudson sez, "Fictionwise used Overdrive to provide DRM encrypted ebooks to their customers and Overdrive has informed them that they will be shutdown on 30 January with no reason given. Since Fictionwise doesn't have the decryption keys, they are not able to provide new versions of the books to all customers."
Fictionwise strives to maintain your purchases indefinitely, but our terms of service do not guarantee they will be available forever. Forever is a long time. We have control of our MultiFormat files and we have control of the Secure eReader format, so that gives us the ability to ensure we will continue to be able to deliver those formats to you. However, as noted above, other formats are delivered through third party aggregators. We do not have legal control of those third party servers. If those third party servers "go dark" for one reason or another, we have no way to continue delivering those files.
And publishers wonder why their customers rip books off on bookwarez sites rather than paying for them...
