How would you describe this book?

I'm curious how others would describe this book "26 Absurdities of Tragic Proportions". It is sometimes called dark humor or macabre, but it is a collection of short tales inspired by Edward Gorey's 'Gashlycrumb Tinies' (Yes, all the children die). There is Mystery, Sci-Fi, Drama, Humor and more. Help me categorize it!

I haven't read it, so this is based upon my familiarity with Gorey and your description: pastiche.
