What’s it about?

The story.

When eleven-year-old Georgie befriends an eccentric retired scientist, she is recruited as the test subject for a thrilling new invention: a virtual-reality experience of the future so real it is impossible to tell from life. At first it is just an astonishing game. But when Georgie glimpses a future in which a deadly virus threatens to kill every dog on the planet — including her own beloved, gloriously smelly Mr Mash — the game becomes deadly serious. Together with her best friend Ramzy and Mr Mash, Georgie must find a way to stop the catastrophe, and to do it almost without leaving the room. Ross Welford blends near-future science fiction, a genuine mystery and a huge amount of heart into a page-turning adventure. Funny, inventive and unashamedly dog-obsessed, it is a story about courage, loyalty and the lengths we will go to for the ones we love — two-legged and four-legged alike.

Fit check

Right for your child?

Where it lands by age

Best for readers aged 9-12 reading independently, with good adult crossover appeal. The near-future sci-fi and mild peril suit older-primary and lower-secondary readers; the dog-centred story also makes it an appealing shared read.
