A mysterious seer, Mélange, sends seventeen-year-old Flora a telepathic warning—beware the Techno-Mage. Before Flora unravels the message, Albert, her dad’s arch-nemesis, kidnaps her father on Terra. She and her brother, Zac, vow to save him. Seeking help, they travel back through time to Earth and find Ben, his girlfriend Lori, and the trusted robot Amorphous.

During the quest, the companions are granted new powers to bend minds and the laws of science. The trail leads them through the multiverse, the afterlife, and beyond. Zac sees Mélange in a vision and is swept away in a riptide of emotion. Mélange tells him to find her on the brightest light in the night sky. The lunar tide pulls Zac, his friends, and foes to the Moon. They fight a desperate battle with Albert for life, power, conquest, and love.
