FOllow the adventures of Ptoni, has Dad and the cat, Ptiddles, on their leaky old trading boat.

They sail up and down the Nile trying to earn a living bartering any produce they can get their hands on.

Dad is a useless businessman and the crew are the laziest group of layabouts ever to get on a boat, so it's up to Ptoni to see things through.

These funny, joke-packed books are the seventh and eighth in the series.

Cartoon illustrations add to the humour and enhance the text.

A special section at the back of the book gives notes on interesting facts about everyday life.

A humorous introduction to life in Ancient Egypt. THE WOBBLY OBELISK - Dad hasn't paid his taxes, so his boat is impounded and he and the lads are forced to join the gang of workers, led by architect Breezbloc, toiling on a memorial to Pharaoh Armenlegup.

But when erected, the memorial obelisk wobbles and Dad is sentenced to beheading!

It's up to Ptoni to sort things out.
