There are a surprising amount of different themes in the book, although the sun explodes one time too many, in my opinion. Some of the stories are sad, some dark, some hopeful, and a few actually funny. The only thing they have in common is that, by the end of the story, something very bad has happened. Well, most times. See? So many kinds of stories!
Because they're so different, it's hard to say anything aside from "they're good." I mean, umm... They're short stories, so the longest take at most an afternoon. Most of 'em are science fiction. I love them all, except "Finis," and maybe the lemming one. The cover uses mainly warm colors.
Look, this is too hard. Just... if you have ever enjoyed anything post-apocalyptic, or any story in which everything goes wrong, or sci-fi stories with interesting twists and mechanics, or bleak stories about human weakness, or hopeful stories about human ingenuity, then you will definitely love at least one of the stories in Bangs and Whimpers.
