In 2020, A Butterfly's Tale was adapted into a junior novel (pending publication).
There was also a booklet printed in 2014 that included 27 illustrated profiles of the major characters and creatures from the series, called The Butterfly Princess: The Profile Collection. Its text was largely based on the character entries from this wiki.
Most of the books were published as e-books originally before being made available in traditional print format.
The books were inspired by illustrations that the author created for his wife of an unnamed winged butterfly princess character. The details of the fictional universe surrounding each illustration became more and more elaborate until the decision was made to write a book that incorporated this wealth of information. In addition to the books, there are also a series of illustrations which are considered canon by the author.
