They are looking at developing a line of smaller, novella sized books.
Think Dragon's Oath by P. C. and Kristen Cast.
The novella size books are approximately 5.25" x 8" and would fit in with the rest of the series, but be slightly smaller to indicate that it's a novella instead of a full story.
I'm curious to see if that's something my readers would be interested in. This give you the opportunity to have a complete set of The Rose Trilogy in print format.
Leave me a comment and let me know your thoughts! :)
