Still a student at the Royal Canterlot University Department of Equinology, young Daring Do faces a summer with no prospect of adventure. That is, until she is approached by Shifty Gaze, who wants Daring to accompany him on an expedition to a mysterious and legendary cloud ruin. Daring does not trust Shifty, but her curiosity forces her to go along. Daring will soon face challenges unlike she ever had before. And what is Shifty planning?

((This story was written as part of a collaborative effort to write the entire Daring-Do series described on the Just For Fun/Daring-Do page on TV Tropes (that page has spoilers). This series consists of sixteen main Daring-Do books and four Young Daring-Do books. I have the pleasure of presenting the fourth book in the Young Daring-Do series: Daring-Do and the Cloud-Held Eternity. I would like to thank Whiles34, my Story Consultant, and Tutis75, my Editor. Enjoy!))
