The Chronos Files

When Kate Pierce-Keller’s grandmother gives her a strange blue medallion and speaks of time travel, sixteen-year-old Kate assumes the old woman is delusional. But it all becomes horrifyingly real when a murder in the past destroys the foundation of Kate’s present-day life. Suddenly, that medallion is the only thing protecting Kate from blinking out of existence. Kate learns that the 1893 killing is part of something much more sinister, and her genetic ability to time travel makes Kate the only one who can fix the future.

Kiernan Dunne abandoned his family ties to help Kate fight the Cyrists, and he's never regretted that for one moment. But he doesn't understand why Kate can't remember that night in 1893 Chicago, when she turned back to face the killer chasing them through the smoky corridors of the World's Fair Hotel. Kate placed the CHRONOS key around his neck and made his eight-year-old self promise to wear it always, and that's a promise Kiernan has never broken.

To stop her sadistic grandfather, Saul, and his band of time travelers from rewriting history, Kate must race to retrieve the CHRONOS keys before they fall into the Cyrists’ hands. If she jumps back in time and pulls the wrong key - one that might tip off the Cyrists to her strategy - her whole plan could come crashing down, jeopardizing the future of millions of innocent people. Kate’s only ally is Kiernan, who also carries the time-traveling gene.

A simple blink is all it takes to yank Pru from the car with her dad into a world of hurt. She awakens in 2305 to find herself pinned under what's left of CHRONOS headquarters, thanks to a recent terrorist attack. Their prime suspect? Her mother, Katherine Shaw. And everyone wants to know how Pru got her hands on a CHRONOS key.

The Cyrists are swiftly moving into position to begin the Culling, and Kate's options are dwindling. With each jump to the past or the future, Kate may trigger a new timeline shift. Worse, the loyalties of those around her - including the allegiances of Kiernan and the Fifth Column, the shadowy group working with Kate - are increasingly unclear.

Simon Rand's life isn't exactly linear, but he's okay with that. He was older than his mother when they first met, and he's traveled pretty much everywhere the CHRONOS key can take him. Much of his childhood was spent in the 1890s on the Cyrist Farm with his friend, Kiernan Dunne, but summer vacations meant hanging out with his grandfather in the 2020s, training to be Saul Rand's right-hand man, and fixing bits of history to help build Cyrist International.
