Rarely, once in a very long time, as in We only see our daughter once in a blue moon. This term is something of a misnomer, because an actual blue moon–that is, the appearance of a second full moon in the same calendar month–occurs every 32 months or so. Further, the moon can appear blue in color at any time, depending on weather conditions. [Early 1800s] [Houghton Mifflin/Answers.com]
Once In A Blue Moon is a series of graphic novels published by Oni Press, written by Nunzio DeFilippis and Christina Weir. The first volume was published in 2004, and featured art by Jennifer Quick. The series is looking for a new artist and has thus yet to publish a second volume, but many volumes are planned. Once In A Blue Moon is the story of Aeslin Finn, a teenaged girl who finds a storybook she hasn’t seen since she was a young child. She discovers the kingdom in the book is in terrible trouble, and for one moment, she wishes she could be there to help. She is transported into the world of the storybook and discovers that it is her destiny to find the last dragon, Blue Moon, awaken him, and team with him to save the kingdom. In her travels, she encounters a rabble-rousing playwright, a tomboy bandit, and secrets from her own family’s past.
