Trivia / Logan Series

• The Shelf of Movie Languishment: The book version of this happened with Olivia, which was pushed back from its original November 1998 release to allow the publishers to promote the Orphans miniseries more. It ended up getting released January 1999.
• What Could Have Been: The title of the final book was going to be Muted Voices but was changed to Olivia (after the narrator of the book), thus ending up the only book in the series to not have the music/sound theme in its title. This was done to make it seem like a standalone novel.
