Black Butler, Vol. 8

When one curtain falls upon the big top stage, another rises behind the
scenes, as young Earl Ciel Phantomhive and his virtuoso butler,
Sebastian, face off against the villain behind the missing children. But
as Sebastian, under orders from his master, single-handedly draws the
gruesome tale to its sad conclusion on one front, battle lines are drawn
on another! With the masterless Phantomhive Manor under attack from the
Noah's Ark Circus and Sebastian nowhere nearby to protect its
inhabitants, is Ciel's home once again headed for the same tragedy that
took the lives of the young earl's parents?
