A gorgeously illustrated celebration of creativity, upcycling and Christmas magic!

It's Christmas Eve at Lily's new house, but Lily misses the old one.

Then, in a moment of magic, she is whisked away to the North Pole! Santa's elfbots need her help to invent new toys from used, discarded ones.

Lily comes to learn that with a dash of imagination, she can make anything - even, perhaps, a new home...

The perfect give for young budding engineers who love to invent things!

Perfect for fans of The Polar Express and Rosie Revere, Engineer.

This is the picture-book debut of Vashti Hardy, the Blue-Peter-Book-Award-winning author of children's novels known for their distinctive fusion of imagination and invention.

Illustrator and rising star Katie Cottle was shortlisted for the Waterstones Children's Book Prize.
