Thanks for the answer, but usually these books have DRM. I bought so far two, I can read them online but do not download on my device. I tried with ADE like they were saying but the application does not recognize them ("says" it can not contact the server, etc ...). Then I do not see the point of spending money for nothing. When I buy a book, I want to have it not to read it just online.
Is there any hope of an update?
