The Silver Stone Society, Book 1 : The Crying Banshee

In a reimagined steampunk London full of spirits of all kinds, three girls that have nothing in common, except for their very special abilities and their huge misfortune, find their stories unwillingly entwined.
All of it because of the somewhat shady Silver Stone Society, lead by a rich, mysterious, German lord and his three sons.

Meet Cathleen, with her loving (and deceased) family, and her somewhat strange ability to see the undead that surround her.
Rebecca (and her card game), who's grandfather died, leaving her with an old library, its moldy attic and a broken mechanical dog.
And meet Neiji, a brave 19 years old girl, who is currently fleeing from her ghoul-possessed family. Even her burning soul cannot undo the spell.

Meet Jack, Chester and Aaron Farrell ; three very peculiar brothers.
Meet their father, the mysterious Josef Farrell (also know as Spiegel) and his strange sense of humour.
Meet his wife, ripped portrait in the basement of their eleventh manor.

Meet the Grim Reaper, the cool dude that made their lives a hell.
