Catachans vs Tyranids Who Are the Deadliest Predators in This New Astra Militarum Novel?

Lazulai is a world beyond the brink, its battle against the tyranids all but lost. Once-magnificent cities lie in ruin. The seas boil. The skies crack. Horrific alien bioforms devour. In mere days the planet will be consumed.

The 903rd Catachan Night Shrikes defend one of the last fortresses still standing. Led by Major Wulf Khan, to die fighting is all that is expected of them until she is given one last mission: to lead a squad through the apocalypse and recover a piece of archeotech that may doom or deliver the entire Lazulai System.

Facing insurmountable odds and zero hope for aid, the major must hold her squad together as they pick their way through an endless xenos jungle. The enemy is merciless, relentless, endlessly adaptable and formidably resourceful... but so too is Khan.
