Fear Itself

Imperial Guard of the 19th Alba Marmorea hold a vital river crossing deep in the verdant forests of Shertore. Their enemy: the inhuman monstrosities of the tyranids. With the deadly aliens attacking ever more frequently and the baleful psychic presence of the Hive Mind pressing in on them, it falls to the commissars and medics of the unit to keep the men together until help can arrive.

A short story from the Fear the Alien anthology.
