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 2029.

Yet moments before death, someone mysteriously appeared and said, 'Take my hand . . .'

But Liam, Maddy and Sal aren't rescued. They are recruited by an agency that no one knows exists, with only one purpose - to fix broken history. Because time travel is here, and there are those who would go back in time and change the past.

That's why the TimeRiders exist: to protect us. To stop time travel from destroying the world . . .

Explore, debate and create with TimeRiders. This new resources kit for teachers and librarians is packed with discussion questions and projects that will engage children in Alex Scarrow's mind-blowing time travel series.

'You HAVE GOT TO read this book!! Have just finished it and i''m dying to read the next one!!! My only complaint about this book is that i''m a bit sleep deprived because i stayed up all night to finish it - couldn''t put it down!! Alex Scarrow has a fantastic way of bringing books to life.... I find myself looking around wondering if there really is a time rider about!!!! I could definately see this on the big screen.'
