A handy reference topic for all members, rather than full discussions. The recommendation, perhaps a link, and a short description of why the work merits our attention, ideally.
Simples but with a dark tone
a) The Gashlycrumb Tinies
by Edward Gorey
Well, Edward Gorey and Charles Addams are artits who made books as well as illustrations with that touch of dark and irony. Addams even married in a pet cementery, he just loved animals.
b)The Ocean at the End of the Lane: A Novel
by Neil Gaiman
c)The Graveyard Book
by Neil Gaiman
I think both books of Gaiman, are intended for a "young adult audience" but the way he describes the situation, the narrative of the stories as well the characters, give us an open world full of misteries and of course dark tones.
