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?
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.
From the bestselling author of the Chronos series comes a page-turning novel of time travel, fast-paced action, and history-changing events.

In 2136 Madison Grace uncovers a key to the origins of CHRONOS, a time-travel agency with ties to her family’s mysterious past.

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.

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.
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?
It’s never wise to talk to strangers…and that goes double when they’re dead. Unfortunately, seventeen-year-old Anna Morgan has no choice. Resting on a park bench, touching the turnstile at the Metro station—she never knows where she’ll encounter a ghost. 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. And when the covert organization seeking to recruit her crosses the line by kidnapping her friend, it will discover just how far Anna is willing to go to bring it down.
What if your mind became your worst enemy?
Struggling with evolving psychic abilities, seventeen-year-old Anna Morgan and her equally exceptional friends are on the run from the ruthless Graham Cregg, leader of a covert operation known as the Delphi Project. Cregg has already killed repeatedly to test Anna’s ability. Now, he and his father, a presidential contender, will stop at nothing to recapture the Delphi adepts, whom they see as weapons to be controlled—or destroyed.
Navigating an increasingly hostile landscape, Anna and her friends form a resistance to rescue those still in the Creggs’ fatal grip. As more gifted kids vanish and public awareness of the Delphi Project grows, so does the opinion that getting rid of the adepts may be a necessary evil.
Yet even as they face off against cold-blooded killers, government operatives, and a public intensely afraid of their psychic powers, the greatest threat to Anna and the resistance may come from within themselves—and their own mysterious abilities could spell their ultimate downfall.
A psychotic killer hijacked her mind and her body. She’s taking them back.
Eighteen-year-old Anna Morgan is on the run from the very government project that created her abilities. Now they seek to weaponize the gift she doesn’t want and can’t control: the invasion of her mind and her body by spirits, some of whom have their own unusual powers. Her latest “hitcher” is a former top Delphi executive. Unlike Anna’s previous guests, this one has taken over, and he’s on a personal mission of revenge.
The target is Senator Ronald Cregg, a corrupt, power-hungry presidential candidate. One of Delphi’s creators, he’s now manipulating the public into believing “psychic terrorists” are a scourge to be eliminated. There’s only one way to stop him, but Anna draws the line at murder.
Pulled into a dark conspiracy, Anna struggles to reclaim her body, mind, and soul as she and the other Delphi psychics join together to fight for their right to exist.
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?
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.
