With a madman in control of the timeline, one wrong move could be the last for time travelers intent on stopping him in this mind-bending novel by the bestselling author of the CHRONOS series.
CHRONOS historians Madi, Tyson, and Katherine and their cohorts are on the enemy’s trail, fixing the mess that sociopath Saul Rand has made of history—and of the Temporal Dilemma rules. Another time shift is on the horizon, and this time, it’s one that reflects Saul’s twisted vision.
When the shift hits, it plunges the United States into a modern dark age where superstition trumps science and seventeenth-century witch hunts are no longer a thing of the past. But Saul has added a new hurdle to this insane reality: he’s hunting the Sisters of Prudence.
Clones of Katherine’s daughter, the Sisters are pawns to be sacrificed on Saul’s time chessboard—unless the team can track him down at the 1967 Monterey Pop Festival and erase him first. Saul is calling the shots, so he’s ahead of them every step of the way. With the clock ticking, this could be the endgame for CHRONOS and, if they fail, for reality itself.
The United States’ past is hijacked in a time-warping adventure of future interdimensional, high-risk games by the bestselling author of the CHRONOS series.
History is turned inside out when off-world travelers challenge Tyson Reyes and Madi Grace to a real-life game of Temporal Dilemma. Three rounds from the opponents and Hitler takes Europe, Pearl Harbor never happens, a fascist cloud hangs over the postwar United States, and CHRONOS itself is erased from existence.
Now Tyson, Madi, and a team of seasoned players must make their moves—in 1930s New York. Jazz and the blues waft from Village clubs. The World’s Fair draws assassins. Madison Square Garden hosts Nazis. And the Manhattan Project never gets off the ground.
Tyson and Madi have only three days to undo the strategy that changed the tides of war and the fate of the world. A surprise survivor from CHRONOS could be their best hope for flipping the timeline. If he’s on their side. But can they risk trusting him when the past, the future, and the lives of millions hang in the balance?
An Amazon Breakthrough Novel Award winner—Grand Prize and Young Adult Fiction.
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?
Publisher’s Note: Timebound was originally released as Time’s Twisted Arrow.
From the bestselling author of the Chronos series comes a page-turning novel of time travel, fast-paced action, and history-changing events.
When two time-traveling historians cross paths during one of the most tumultuous decades of the twentieth century, history goes helter-skelter. But which one broke the timeline?
In 2136 Madison Grace uncovers a key to the origins of CHRONOS, a time-travel agency with ties to her family’s mysterious past. Just as she is starting to jump through history, she returns to her timeline to find millions of lives erased—and only the people inside her house realize anything has changed.
In 2304 CHRONOS historian Tyson Reyes is assigned to observe the crucial events that played out in America’s civil rights movement. But a massive time shift occurs while he’s in 1965, and suddenly the history he sees isn’t the history he knows.
As Madi’s and Tyson’s journeys collide, they must prevent the past from being erased forever. But strange forces are at work. Are Madi and Tyson in control or merely pawns in someone else’s game?
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.
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. But their growing bond threatens everything Kate is trying to rebuild with Trey, her boyfriend who can’t remember the relationship she can’t forget.
As evidence of Saul’s twisted mind builds, Kate’s missions become more complex, blurring the line between good and evil. Which of the people Saul plans to sacrifice in the past can she and Kiernan save without risking their ultimate goal—or their own lives?

These mental hitchhikers are the reason Anna has been tossed from one foster home and psychiatric institution to the next for most of her life.
When a chance touch leads her to pick up the insistent spirit of a girl who was brutally murdered, Anna is pulled headlong into a deadly conspiracy that extends to the highest levels of government. Facing the forces behind her new hitcher’s death will challenge the barriers, both good and bad, that Anna has erected over the years and shed light on her power’s origins.

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?
