Mundo de Aventuras #37

In "O Segredo do Castelo de Marvyn," Dale Makinnie arrives at the foreboding Marvyn Castle on a mission from Artur, only to find a household poisoned by old grudges and hidden lies. With a ruthless usurper, a desperate noblewoman, and a young woman who seems to vanish into the shadows, Dale must navigate a web of deceit where every ally could be a threat—and even courage may not be enough.

In the scorching Australian desert, an impossible volcano erupts—spewing forth a subterranean people with steel legs and a hunger for conquest. Captured and forced to guide them, Mike Steel must race against time to save Prudence and Mopo-ke, dangling above the abyss, as sabotage, broken radios, and deadly terrain test every move. With no allies and only cunning to rely on, survival hinges on turning the invaders’ own weapons against them.
