Dak Smyth and Sera Froste are heroes. They fixed the Great Breaks in history, setting the world on its proper course at last. Or did they? Strange things are happening in the present, and it all points to more trouble in the past. But the time travelers have no idea why the SQ is so interested in a Chinese alchemist, the trial of Galileo, or a Russian dog named Laika. With the clock ticking and no Hystorians to help them, this time Dak and Sera may not be able to fix what has been broken. . . .
