History Literature / TimeRiders

* FutureFoodIsArtificial: In the 2050's humanity has damaged the ecosystem to the point that people have to survive on artifical food.

* ArchivedArmy: The team are joined by the likes of [[spoiler:UsefulNotes/AbrahamLincoln and the apparent Myth/RobinHood]]. However, they can't stay permanently.

* BittersweetEnding: [[spoiler: Sal, Rashim and Foster]] may be dead, but [[spoiler: Liam stays with Bob and Becks and Maddy likely goes back to be with Adam.]]

* ChristmasEveryDay: When the group are based in New York, they live in a time bubble that encases them in the 10th and 11th of September 2001 over and over again. Waldstein's logic was that nobody would notice any of their odd behaviours while such a drastic event was happening. [[spoiler: Though ultimately, it did the opposite and made them extremely suspicious to the US government, who pursued them when they accidentally attracted their attention.]]

* CloseEnoughTimeline: A frequent occurrence in the team's time fixes is that they can't correct the contaminations perfectly, namely preventing any trace of their existence being known, but they can correct the course of history. For example in The Eternal War, the group prevents Lincoln being run over by a stampede of horses before he can accomplish anything he did, but they can't prevent the horses from bolting in the first place, because they can't stop what made the problem occur: [[spoiler: Joseph Olivera's clumsy and panicked dash back in time that ended with his body being fused with one of the horses, killing him and startling the rest.]]

** This also happens in ''Gates of Rome''. Project Exodus, launched from the 2070s, involved aiding the Roman Empire in changing history for the better with guidance from the future, firepower, hover boards and the most advanced support units ever created. Unfortunately, that backfired when the Romans decided to [[spoiler: ditch the help and just keep the tech]].

* HistoricalPersonPunchline: The cast stay in a dingy basement in Victorian London, with an aggressive landlord assisted by a young man named Bertie. Sal confides in him and the two grow attached to each other. [[spoiler: Bertie is actually H. G. Wells, and an entry from his journal is included in the end of ''The Mayan Prophecy'' written later in his life, in which he expresses disbelief in what he remembers of the TimeRiders, but admits to using them as inspiration for "Literature/TheTimeMachine".]]

* NoEnding: It's left to us to decide what happens to Maddy at the end of The Infintity Cage. She's given the choice to [[spoiler: go anywhere in time alone. It's heavily implied she went to be with Adam in his time, but not outright said.]]

* Chronoscope: Tachycons can be utilised to take a pinhole-like snapshot of any moment anywhere, past or future, for the group to view with their technology. It is risky and uncertain, but frequently used throughout the series.

* RippleEffectIndicator: The three teenage main characters police the timeline, living through the same two days (10/09/01 through 11/09/01) in a loop. One of them, Sal, is responsible for walking around the city of New York during the days before and of 9/11 attacks, checking everything for changes caused by the Ripple Effect. Due to them living in a time bubble, they all have RippleEffectProofMemory.

* GodwinsLawOfTimeTravel: [[JustifiedTrope Justified]] in the first book: Paul Kramer intentionally changes history to ensure that Germany wins WW2 because he believes that this will prevent the BadFuture that he grew up in. Unfortunately, he goes insane fifteen years into his reign as the new ruler of Germany and sets off a doomsday device, resulting in TheEndOfTheWorldAsWeKnowIt. Thankfully, this is fixed by the end of the book.

'''''Time Riders''''' is a series of nine Young Adult science-fiction novels by Alex Scarrow. Three teenagers find themselves saved moments before death by a mysterious agency, who recruit them to travel through time to correct errors in history caused by tampering time travelers from the future. Eventually, the trio discovers that the agency has far more secrets hidden away than they had originally thought.

* AgeAppropriateAngst: Maddy, Sal and Liam are all just teenagers, a valid reason for all of them being driven to tears at least once over the course of the series. Dealing with figuring out the Agency's secrets proves to be even worse for them than the much older [[TheObiWan Foster]], who is already angsty enough as things are.

* DarkerAndEdgier:

%% * NoEnding: It's left to us to decide what happens to Maddy. She's given the choice to [[spoiler: go anywhere in time alone. It's heavily I,plied she went to be with Adam in his time, but not outright said.]]
