Yes - go to the Table of Contents page - you can reach that from any page by touching the page and a menu will appear at the top of the screen and the second to most-left icon, touch that and it will take you to the Table of Contents. On that page you'll see, on the right hand page, above the Table of Contents, two buttons. One says 'Table of Contents' the other says 'Bookmarks'. Touch the Bookmarks button and all your bookmarks will be listed.
Then just touch the one you want to go to.
