The Dread Lions of Rufiji

Kicked out from their pride, two lion brothers arrive on the farmed flood plain of the Rufiji River. Half-starved, they must carve out a new hunting ground before the next big rains ... or it will be the birds who feast.

500 miles north, four teenage trainees leave their film base in the Serengeti and head to the headwaters of the Rufiji. Their search for bush pig sites will cross an invisible boundary into a new kingdom ... where the law of nature still rules.


The Dread Lions of Rufiji is the first exciting story in the Sons of the Serengeti adventure series.

WHAT READERS ARE SAYING:

“Honestly I’m not a fantastic reader and I usually don't just pick up a book and start reading but in this case I couldn't keep it out of my hands over the Easter holidays ... would totally recommend this book if you’re into thrilling nature style adventures"

The Hunt for the Kaiser's Lost Gold

In the dying days of World War 1, the Imperial German Army races to hide gold bullion mined from Lake Victoria.

100 years later, with the film camp at Ndutu in its death throes, this treasure offers a lifeline. And one of the rising stars is a direct descendent, and heir, to the last secret of a dying man.

As sinister eyes track, and Machiavellian minds plot, the hunt for the Kaiser’s lost gold turns into a race to survive!


The Hunt for the Kaiser's Lost Gold is the third exciting story in the Sons of the Serengeti adventure series. It will be available in late Summer 2026.

SONS of the
SERENGETI

…is an adventure series anchored in East Africa.

Based at a film camp in the Serengeti, four film trainees cross swords with ivory smugglers, gold bullion hunters, the live-wildlife trade, man-eater attacks, and more. Their attempts to overcome, thwart, expose, and survive, put them firmly in the crosshairs of the most dangerous organisation on the continent.

These adventures take them from the interior of the Congo Rainforest to the Highlands of the Ethiopian Plateau, from the snow of Kilimanjaro to the scorched earth of the Danakil Desert, and out across the Indian Ocean to the Bay of Bengal and beyond.

Their courage, wits, endurance and mettle will be tested to limits few adults ever experience.

CHARLES CHALLIS

In 1992, after a 12,000-mile motorbike journey from the UK, Charles arrived in East Africa. Here a Tanzanian friend invited him to stay and run a butterfly project. At this time he met members of the Monduli Juu Maasai community - and many adventures were had.

In 1996 Charles married into a family living on the edge of Arusha National Park. The relationship and antics of his new sons and their best friend, and the time they spent in the Serengeti – along with wildlife-related challenges - was the inspiration for the adventure series.

Lion-human interactions had been occurring in the Rufiji and Lindi regions of southwest Tanzania, especially from the mid 90’s to the mid 00’s.The Dread Lionsexplores the dilemma of living with large predators.
