Madagascar was only the beginning. Now it’s Africa’s turn to bleed.

Billionaire philanthropist Julian Harlow funds an expedition deep into the Congo to verify reports of a prehistoric titan, a long-necked herbivore long dismissed as myth: Mokele-Mbembe, the “Dinosaur of the Congo.” The recent discovery of a vibrant world beneath the surface of Earth makes the animal’s existence more plausible than ever.

Suddenly, the team is attacked and savagely torn to pieces by a pack of fast-moving wraiths. Only two men survive. One vanishes farther into the jungle. The other returns to basecamp battered, bleeding, and with a warning.

There’s something else out there.

Desperate for answers, Harlow turns to the only people capable of uncovering the truth—experts who know more about hyper-evolved creatures than anyone alive: Ian Hunt and Mackenzie Moore, founders of the Madagascar Protection Agency.

But even they aren’t prepared for the horrors that await them in the heart of the Dark Continent.
