A.J. Kyler is the pseudonym of the authors Annie and Jay: two close friends who met over ten years ago and have been writing for just as long. Creating worlds and stories is their favorite pastime, a hobby they kept between themselves until Annie jokingly suggested to self-publish a book—and Jay took it seriously. They love reading and writing, usually stay up far too long to come up with new characters and ideas, and take regular "workations" during which they hike through forests and visit castles—and plot their next book.
