I lent a book to a friend of mine by posting it on FB. She says she can't downlowd it to her Nook. She needs me to re-lend it to her (she read how to accept them). How to I take the book back and re-lend?
You can't re-lend books. You may lend a book only one time, to one person.
Try calling customer service, perhaps they can reset this book for you since it didn't go through.
