In book eight of the Library of Illumination where books literally come to life, a silent "Oops!" hangs in the air. Teenagers Johanna Charette and Jackson Roth have allowed a sneaky shapeshifter to slip right through their fingers. The good news is that he's now trapped between the layers of time and space with their Terrorian nemesis, Nero 51. The bad news is the Terrorian still wants to control all the Libraries of Illumination, while the shapeshifter wants to dominate everything else, and they're doing everything possible to break free of their constraints. Who knows how long the Illumini system will remain safe? It's taking a toll on Johanna and Jackson, who are smack in the center of everything as they struggle to protect the libraries' legacy. Can you spell s-t-r-e-s-s? The pressure is driving a stake between the teens, and their mercurial romance could be over before it has truly begun.
