Time riders

When liam and his new support unit,Becks,are accidentally pulled through a time window to
The prehistoric past,along with a high school class
On a field trip,the entire mision to save the creator
Of time travel seems lost.
Not only will the changes they make in the past
Dangerously affect the pressent, but it seems
Unlikely that the group will survive in an era
Filled with ruthless predator.
Even with Maddy and Sal frantically trying to piece
Together what went wrong and send assistance
From modern-day New york, unless Liam
Finds a way to send a message sixty-five milion years into the future, humans may no longer walk
The eath. Will the team be able to reunite, escape
The prehistoric hunters, protect time travel's
Inventor, and save the world?
