Honour Guard — Dan Abnett

COMMISSAR GAUNT and his Ghosts are back in action at the forefront of battle on a vital shrine-world of the deepest tactical and spiritual importance. But the vile forces of Chaos will never allow them to hold their prize for long and, as the counter-attack rages, Gaunt is sent after the most priceless relic of all: the remains of the ancient saint who first led humanity to these stars.
