Who is this for?
A Warhammer 40,000 Novel of Survival Against the Tyranid Hive Fleets
In the darkness of the 41st millennium, few threats are as terrifying as the Tyranids — a devouring swarm that learns, adapts, and consumes everything in its path. When a decorated Lieutenant of the Ultramarines detects the first signs of an approaching invasion, he launches a desperate counteroffensive to save the Imperial world of Regium.
What follows is a brutal struggle for survival as Imperial forces face wave after wave of alien horrors. Every tactic, every sacrifice, and every maneuver matters — because the enemy is evolving with terrifying speed. As morale falters and defenses crumble, the Lieutenant must find a way to hold the line long enough for reinforcements to arrive… if they arrive at all.
Leviathan plunges you into the heart of a massive Tyranid incursion, showing the courage, tragedy, and determination of those who stand between the Imperium and total annihilation.

Details
Warhammer 40,000 is a galaxy defined by unending war, and the Tyranids represent one of its most horrifying enemies. Unlike any conventional foe, they are a living, evolving force — a swarm that absorbs the knowledge of every battle and grows deadlier with each encounter.
In Leviathan, the Ultramarines and their allies must defend Regium against this overwhelming menace. As the campaign unfolds, commanders struggle to adapt to an enemy that constantly shifts tactics, while soldiers on the ground face nightmarish creatures bred specifically to tear them apart.
This novel gives you a front-row view of large-scale Imperial warfare, combined with tense personal stories of courage and sacrifice. If you want to experience what it truly means to fight the Tyranids — and why Hive Fleet Leviathan is feared across the galaxy — this is the perfect place to start.
