When an alien invasion threatens the existence of all the knowledge in the universe, eighteen-year-old Johanna Charette and seventeen-year-old Jackson Roth must rely on their wits, guts, and pluck to save the fantasy-come-to-life world of the Library of Illumination. It wouldn’t be so bad if Johanna and Jackson weren’t the ones responsible for breaching the portals to a dozen distant worlds. Now, outside forces are causing shock waves in the space-time continuum, and if that isn’t awful enough, someone from another dimension is trying to steal a book of powerful spells created by a very famous wizard. At first, traveling to other realms in a time machine seems like a fun perk. However, discovering some inhabitants want to obliterate the teens doesn’t leave them with a warm, fuzzy feeling. Instead, they find themselves forced to sacrifice their own welfare and the safety of their loved ones for the greater good.
