Illuminated: The Fall of Terra:

Terra. An ancient and nearly perfect world where love and peace reign, and where everyone has a divine Calling that serves the All. If anyone experiences negative thoughts or emotions, the goddess, Alma, will sense their disharmony and guide them out of pain into love. It's nearly time for Mylo's Calling Day, but he has no idea what his Calling may be—and without it, he is lost. Can Alma help him find his true path without revealing a terrible secret? Can she resist falling in love with the empowered and emboldened version of Mylo she helped create through their union? And can she trust him to protect the crystal Scriptures that hold the true history of Terra and the Knowing of the All? Who will be the Carriers of Light? Because the Darkness is coming, and soon.
