If you can only see the first page of an eBook open in Adobe Reader, or a new PDF is opened each time you turn an eBook page, this is probably due to a setting in Adobe Reader (or your PDF reader.) To correct this, you should change your setting to open PDFs within your web browser's window.
To change this setting in Adobe Reader:
Launch Adobe Reader.
Click the Edit menu in the top toolbar at the top of Adobe Reader.
Select Preferences from the resulting drop-down list of options.
Select Internet in the left-column of the resulting Preferences menu.
Mark the check box for Display PDF in browser.
