Time Travelling with a Tortoise - Grand Format

Al Chaudhury travelled back in time to save his father's life. And it worked - Al's dad is alive again and life is back to the way it should be. At least, that's what Al thinks. But when an accident robs Al's beloved Grandpa Byron of his world-beating memory, Al is forced back in time again - and this time, someone gets left behind, trapped in a prehistoric dimension. Now Al is forced into a rescue mission to recover his friend from the past - and to make sure that there will be a future waiting for them all.
It turns out time travel is far more complicated than Al thought... The funny, heart-warming and extraordinary new adventure from Ross Welford, bestselling author of Time Travelling with a Hamster.
