Ann Rule or Anne Rice,
Neither author is very nice.
Gentle readers will complain
If you give them either name.
Give Jan Karon to this bunch.
Read John Gardner with your lunch.
Which John Gardner, can you tell?
There's James Bond or Grendel.
When matching reader to a book,
You must take a careful look.
Readers are picky, you will see
When you do readers' advisory.
