I enjoy reading other people's opinions about things, and these City Secrets Insider's Guide books are right up any 'guide book' lover's alley. They are compilations of short essays written by award-winning novelists, writers, poets, directors, producers etc... all revealing and recommending their favorite forgotten, underappreciated and little-known movies and works of literature. They would make a perfect gift for many people on my list that are tricky to shop for. I received them in the mail the other day and was really delighted with their content.
You can find City Secrets Movies and City Secrets Books and the rest of the series including City Secrets travel titles here.
