The Pirate Kings (TimeRiders, #7)

ISBN moved from less recent edition here

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...

Relocated to 1888 Victorian London, the TimeRiders joyride back to 1666 to witness the Great Fire of London. In the ensuing chaos, Liam and their newest recruit, Rashim, find themselves trapped between the fire and the Thames. They escape on-board a river boat, only to be confronted by an unscrupulous captain with his heart set on treasures of the high seas ...

Can Liam and Rashim survive the bloodthirsty and barbaric age of piracy long enough to be rescued?
