Time Jumper Books in Order

Time Jumper is Falconer's three-book edition of the Emily Heart story, and it leans hard into motion. Emily is fifteen, altered against her will, and living with powers she barely understands. The smallest burst of fear, anger, or panic can throw her through time, which means even ordinary stress becomes dangerous.

That premise gives the books their energy. Emily is not learning to use her abilities in a safe place. She is trying to survive on the street, dodge gangs, avoid police attention, and work out who changed her DNA before someone else gets to her first. The city around her is harsh and immediate. Shelters, side streets, hidden rooms, and quick escapes matter just as much as the larger science fiction mystery.

Then there are the people who keep complicating her life. Jim Miller has been following the trail of a girl who never seems to age, and his curiosity turns into something closer to protection. Derek draws Emily toward normal human attachment, which is a problem when normal has already disappeared from her life. Junie pushes Emily to care when the safest choice would be to stay detached. And hovering over it all is the deeper threat behind the experiments, including the unsettling figure of the Orange Man.

The three books, Shadow Games, Shadow Prey, and Shadow Justice, build like one continuous chase. Emily's powers become harder to manage, the mystery behind them gets darker, and the cost of every decision grows heavier. What begins as a survival story turns into a broader fight over identity, memory, and control. Emily keeps asking the same basic question in different forms: if someone changed her at the deepest level, what part of her still belongs to her?

The tone is quick, tense, and very readable, with a YA heart under the sci-fi setup.

If you like stories that mix relentless pursuit with a damaged but stubborn lead, this series delivers that. If you later spot Glassford Girl or Girl Out of Time on Falconer's list, that is because Emily's saga has appeared in more than one release format over the years. Time Jumper is one of the clearest ways to follow the middle version of that journey.
