Du vortex à l'abysse

The second volume of Tunisian author Khaoula Hosni's French-language science-fiction trilogy La Fosse de Marianne (Into the Deep), Du vortex à l'abysse drives the story begun in Le cauchemar du bathyscaphe toward its climax. The descent into the ocean's depths grows more perilous and more strange, as the crushing pressures of the abyss, the failing machinery of survival, and the frayed nerves of those trapped below collide.

Where the first book set the trap, this one springs it, escalating the danger and the dread as the boundary between the physical deep and the psychological one dissolves.

A tense, atmospheric work of deep-sea science fiction and psychological suspense, it deepens the trilogy's central descent before its final resolution in La Fosse de Marianne.
