Thun'da, King of the Congo #4

When leopards and gorillas begin enforcing a brutal tribute system across the Congo—demanding gold and diamonds from the tribes—Chief Masumba and other leaders who refuse to pay suffer deadly consequences. Thun'da receives his own death threat and must uncover the sinister force driving the animals to madness, a mystery that deepens when he rescues a hunter named Darla Kenyon from a raging beast and learns she may hold the key to the jungle's curse. Together they pursue the truth to a hidden cave, where the answer—and a shocking revelation about Darla's past—await.

In a jungle realm where ancient tribes clash and fate hangs in the balance, Irana, queen of the Amazons, sets her sights on Thun'da, determined to claim him as her own. With Pha at his side and the wilds of the Congo closing in, Thun'da must outwit both the relentless queen and the dangers of the untamed land—while Irana’s vow of revenge begins to take shape.

When explorer John Farris discovers a mysterious jungle weed that can enslave a man's will, he doesn't hesitate to use its smoke on Thun'da himself, forcing the Congo King and his companion Pha to reveal the location of Africa's greatest hidden treasures. But as Farris grows drunk on his newfound wealth and carries Pha away toward civilization, Thun'da begins to break free from the drug's grip—and nothing will stop him from reclaiming what was stolen.
