Shield of Baal: Devourer

The deadly worlds of the Cryptus System, always beset by the gravitational and radioactive forces of their twin stars, have come under a new threat - the xenos might of the Tyranids. A tendril of Hive Fleet Leviathan has reached the Cryptus shield worlds. The Imperium musters its strength, for the aliens must be stopped here, as next in the Hive Fleet's path is the homeworld of the Blood Angels Space Marines, Baal itself.
