Cognation Academy has always harbored mysteries beneath its enchanted, tech-fueled campus, but certain alcoves hold more sinister secrets than anyone suspected. Last fall, the cutting-edge Android Inception Program flipped Charlotte Blythe's world upside down as she risked everything to save her android friends, Isaac and Denton. With Isaac's future still in jeopardy, Charlotte throws herself into the annual enigma tournament and campus-wide battle over androids' rights. As reality and illusion converge, a cryptic journal from Cognation's founder awakens an unexpected foe and opens a decades-old cold case with explosive implications. Only Charlotte and her friends have the courage to search for the missing clues before it's too late.
