: The novels revolve around three teens who are recruited by an agency known as 'The Agency' just before their deaths. The Agency was set up by Roald Waldstein to protect the established set of events throughout history and to fix it if it is tampered with. They operate from their field office underneath an archway of the Williamsburg Bridge in New York City in a two-day 'Time Bubble', on September 10 and 11, 2001. Each novel revolves around a major change in the historical timeline and the team must work with each other to fix it with the help of their 'support units' – cyborgs who can mimic human behavior. Later in the series the characters move to a second base under the Holborn Viaduct in Victorian London.
: Liam O'Connor should have died at sea in 1912.
Maddy Carter should have died on a plane in 2010.
Sal Vikram should have died in a fire in 2026.
But all three have been given a second chance - to work for an agency that no one knows exists.
Its purpose: to prevent time travel destroying history . . .
Project Exodus - a mission to transport 300 Americans from 2070 to 54AD to overthrow the Roman Empire - has gone catastrophically wrong. Half have arrived seventeen years earlier, during the reign of Caligula.
Liam goes to investigate, but when Maddy and Sal attempt to flee a kill-squad sent to hunt down their field office, all of the TimeRiders become trapped in the Roman past.
Armed with knowledge of the future, Caligula is now more powerful than ever. But with the office unmanned - and under threat - how will the TimeRiders make it back to 2001 and put history right?
