I haven't read either, but my boyfriend loves Sue Grafton's books so I read 'A' is for Alibi, and I found it to be a thoroughly enjoyable time.

And King is an excellent storyteller. I loved his books as a kid but haven't read The Shining.

Are there any other considerations? Are these genres or authors new to your group or continuing along a theme or pattern? What types of books do you like usually? Etc?
