Sir William the Marshal, legend in his own time, has promised to go on
crusade, a vow made to his Young King as he lay dying. But when the
Oliphant, legendary war horn of Roland, is stolen by the lethal
Assassins, he's charged with returning the relic in order to stop the
very thing he'd vowed to undertake--a crusade; this one engineered by
the thieves.
With his small band of trusted companions--Sir Baldwin, his tourney
compatriot; Eustace, his squire; and Henrik, the giant Norseman--William
sets out to take back the relic. But treachery abounds, and when William
loses two of his companions, he discovers an unlikely ally--Da'ud, an
Assassin himself, bent on taking the Oliphant from the heretic faction
that has stolen it. The three fight their way across land, sea, and
desert, only to find themselves facing an army...and the Oliphant within
their grasp.
