There are eight Grk books, each set in a different country. There is no particular need to read them in the correct sequence, but this is the order in which I wrote them:

A Dog Called Grk
A boy called Timothy Malt is walking home from school when he finds a lost dog. That dog is called Grk. Together Tim and Grk travel to Stanislavia, a small country in Eastern Europe, and try to find Grk’s owners.

Grk and the Pelotti Gang
In Brazil, Tim and Grk chase a gang of bank robbers.

Grk and the Hot Dog Trail
In New York, Tim and Grk follow the trail of a missing statue, the Golden Dachshund.

Grk: Operation Tortoise
In the Seychelles, Tim and Grk save the giant tortoises.

Grk Smells a Rat
In India, Tim and Grk rescue local children from slavery.

Grk Takes Revenge

Grk Down Under

Grk and the Phoney Macaroni

A Dog Called Grk, was shortlisted for the Branford Boase Award and won the East Sussex primary schools books award; Grk and the Pelotti Gang was shortlisted for the Blue Peter Book Awards in the “The Book I Couldn’t Put Down” category. The Grk books have been on the Booked Up Scheme and the Boys into Books list. The series has been translated into twelve languages.
