A Dog Called GrkPaperback, 9 October 2018

When Tim finds an abandoned little dog outside his house, he can't just leave him there, even though his parents hate the idea of pets in their house.
But it turns out that this is no mere homeless pooch - he's Grk, the missing pet of the ambassador of Stanislavia. Tim wants to reunite them, but it means that he will become embroiled in the dangerous politics of a secretive Eastern European country. It's not long before Tim finds himself breaking into a high-security prison, flying a helicopter, and making a nail-biting race for the border - all for the love of a very special dog.

Shortlisted for the Branford Boase Award.
