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 . . .

Hunted by cyborg assassins from the future, the TimeRiders must abandon New York and go on the run. They escape to Victorian London and the streets where Jack the Ripper roams. But, before they can establish their new base, they make their most shattering discovery yet - and it will change everything . . .

The sixth thrilling instalment in the bestselling TimeRiders series by Alex Scarrow, set in Victorian London. Alex's first TimeRiders adventure won the Red House Book Award older readers category, and was Penguin UK's first ever number one on the iBookstore.
