Some books are available as both audio and e-books so you can change between the formats.
If you are listening to the audiobook and click on the book cover you get the option to Read the e-book. Click on Read and you can continue with the book as an e-book. You can turn the page by swiping your finger from right to left or left to right to go back in the book.
To change to the audiobook just click on the paragraph where you stopped reading so the text is highlighted. You will now have a Listen-button. Click on it and the audiobook will start playing from the paragraph you have marked.
It is not possible to read and listen at the same time.
In some cases where the e-book and audiobook is too different or is not able to sync you can not change between the formats. If you start to read and then go to the books detail page and choose listen it will start from the beginning.
Keep in mind: E-books are not available in Windows Tablet or PC
