Can I sample books before I buy them? How do I remove a book sample?

Most books you'll find on Fable will have Samples available, which you can save to your bookshelf by clicking on the book detail and then selecting Sample. This will send the book to your Fable Bookshelf, where you can click the 3 dots next to the book to remove the sample, save it to a list, or find a link to purchase the full book. (Purchasing the book will replace the sample in your bookshelf.)
