Soulless: The Manga, Vol. 1

The life of a spinster in Victorian London isn't an easy one on the best
of days, but such a life becomes infinitely more complicated when said
spinster is "soulless" - a preternatural bridging the gap between the
natural and supernatural worlds. Miss Alexia Tarabotti has this unique
distinction, and when she is assailed at a formal gathering by a rove
vampire, an encounter that results in the death of the half-starved
creature, her circumstances become exponentially more complicated
indeed! Now caught up in an intrigue with life or death stakes, Alexia
must rely on all her talents to outmatch the forces conspiring against
her, but it may be the man who has caught her eye - Lord Conall Maccon -
and their budding flirtation that truly drives her to her wit's end!
