On the list of authors mentioned in the "Writers Mentor", I picked up a book by Lorrie Moore from the library. It was a quick read of short stories with titles like "How to be the other woman" and a story about a woman who has cancer and has decided on suicide, and another story about a woman who confronts her husband having an affair and stabs him. The story that I liked best was probably "What is Seized". None of these stories were happy though. There is a lot of loss mixed with the love, and some dark humor as well. The back cover calls these "nine glittering tales....". I'm not sure I would describe it that way.
Here's a link if you are interested in checking it out yourself.
