What’s it about?

The story.

Al Chaudhury once travelled back in time to save his father's life – and it worked. His dad is alive again, and life is back to how it should be. But when an accident nearly kills his beloved Grandpa Byron and forces Al back in time once more, he leaves someone behind, trapped in another dimension forever. Now Al must journey through time yet again: not only to rescue his friend from the past, but to save Grandpa Byron's life and make sure there's still a future waiting for them all. This standalone-friendly sequel to the bestselling Time Travelling with a Hamster brings back Ross Welford's clever time-machine logic, his ticking-clock tension and his gift for characters you truly care about. Beneath the paradoxes and the pace runs a tender story about family, memory and the people we can't bear to lose – funny and thrilling, but with a genuine ache at its heart.
