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?
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?
Stay tuned for the final chapter in the Enter Haddonwood trilogy.
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?

When the rusted-out remains of a vehicle with a unique vanity plate are hauled out of the Freedom River, journalist Ruth Townsend and her best friend, Wren Lawson, think they've finally learned the truth about the disappearance of their high school friend, Tanya Blackburn. The rest of Thistlewood may have believed that Tanya simply packed up and headed for the bright lights of Nashville, but the story never made sense to Ruth and Wren, and the mystery has haunted both of them for more than three decades.
A set of paintings left for Ruth at the estate sale of a former teacher seem to contain clues about what really happened to Tanya in the summer of 1987. But when Ruth unboxes the collection, she discovers that Wren may be keeping a few secrets of her own.
Thistlewood is all decked out as a picture-perfect Christmas village and the ideal backdrop for a holiday movie. The entire town is abuzz with excitement until one of the actors, Oscar-winner Audrey Shaw, turns up dead in her trailer on the set.
Ms. Shaw's star faded decades ago, and her failure to show up for filming has put the production several days behind, at a time when the cast and crew would prefer to be home with their families. Rumor has it that Shaw was hitting the bottle again, as well.
The local sheriff, the mayor, and the film's producer all insist that Shaw's death was accidental. Ruth and Cassie are certain it was murder, but can they prove it--and locate the town Santa's missing reindeer--before the suspects pack up and head home to California on Christmas Eve?
