To view the reading order for the "Dark" series, visit the ChristineFeehan.com home page, and click Dark Series. The series page lists the reading order under the Dark Series FAQs heading. While the site has a separate page dedicated to Dark Series FAQs, the reading order on the series page has more recent books on its list.
Readers don't need to read the "Dark" series in order, as each book has a standalone plot that doesn't require information from previous books in the series to understand. However, reading the books in the correct order enhances the experience as the reader can understand the characters' world better. One of the author's books that isn't part of a series, "The Scarletti Curse," is related to the "Dark" series, as the descendant of characters in that book is part of a book in the "Dark" series.
Each book in the series focuses on different characters. However, some characters are in multiple books, and certain books in the series are closely related. For example, Feehan considers "Dark Challenge," "Dark Fire" and "Dark Melody" to be a trilogy within the series.
