I have seen authors asking this question on facebook lately and I have to say that I do. In thinking about it though, I would say I mostly re-read books from series that I love. This week I have re-read Cherise Sinclair's Dark Haven/Mountain Masters books in preparation for the new novella, Master of Freedom.
I have also re-read Kristen Ashley's Dream Man series. There aren't any new books in the series, I just love those alpha heroes and the crazy women who love them.
So I ask, what books do you read more than once?
