CHRONOS historians travel to the past to observe history as it happens.

But Saul Rand isn't content with simply observing. His plan: reshape history by creating a new religion and then stop anyone by any means necessary who doesn't fall into line. In The CHRONOS Files, seventeen-year-old Kate travels through time to retrieve CHRONOS keys before they fall into the hands of Saul and his Cyrists, all while trying to tread through the past without erasing the memories of those she loves or her entire existence.


Timebound (The CHRONOS Files, #1)

2013 Winner Amazon Breakthrough Novel Award Grand Prize and Young Adult Fiction Winner

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. Risking everything, she travels back in time to the Chicago World's Fair to try to prevent the murder and the chain of events that follows.

Changing the timeline comes with a personal cost if Kate succeeds, the boy she loves will have no memory of her existence. And regardless of her motives, does Kate have the right to manipulate the fate of the entire world?

Timebound was originally released as Time's Twisted Arrow.

Time's Echo

Time's Echo (The CHRONOS Files, #1.5)

This Kindle exclusive CHRONOS Files novella gives Timebound readers a glimpse at Kate in another timeline and helps set the stage for Time's Edge, the second book in The CHRONOS Files Series.

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.

When Kate suddenly vanishes after a Cyrist-engineered time shift, that hidden medallion is Kiernan's only hope for finding her. He returns to the Cyrist fold to look for clues, but his search will lead him back to the question that has haunted him for years--what really happened after he left Kate at the World's Fair Hotel?

Time's Mirror

Time's Mirror (The CHRONOS Files, #2.5)

The second CHRONOS Files novella follows Prudence's story from her fateful first journey with the CHRONOS key to the point where her story intersects with Kiernan Dunne in the first novella, Time's Echo. It also helps sets the stage for Time's Divide, the third and final book in The CHRONOS Files, coming from Skyscape in October.

It's 1984 and the only things on Prudence Pierce's mind are seducing her violin instructor and, with the help of her sister Deborah, avoiding the wrath of their mother for stepping out of the house dressed like Madonna. Her mother might also be a teensy bit angry about the medallion Pru swiped from the attic--a medallion that glows lime green and has an oddly hypnotic, holographic effect when Pru holds it in her hand.

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.

Pru is convinced that the key is the answer to all her problems. She'll use it to stop her mother, fix her relationship with Deb, and even restore CHRONOS, so that her new friend Tate can return to the job he loves.

She can't do it alone, however. Fortunately, she finds Saul Rand, and he's more than willing to help.



Time's Divide (The CHRONOS Files, #3)

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.

Kate will risk everything, including her life, to prevent the future her grandfather and the Cyrists have planned. But, when time runs out, it may take an even bigger sacrifice to protect the people she loves.

Simon Says

Simon Says: Tips for the Intrepid Time Traveler (The CHRONOS Files, #3.5)

A CHRONOS Files Novella

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 and everywhen 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.

But that's just Simon's day job. His true passion is time tourism--jumping right smack into the middle of historical events to see what really happened. Sometimes, however, simply witnessing an event can change it, and when Simon and Kiernan investigate the death of Simon's teenage obsession, Marilyn Monroe, it may just unravel the history he knows and loves.
