Recently I read a set of books by an author named Karen Hancock  http://www.kmhancock.com/

Anyhow, she has 3 books so far in her the Legends of the Guardian-King series. In her second and third book the main character does a bit of slinging.

She is a Christian Fantasy Writer.

Anyhow...I will try and get over the fact that I am not being as original as I thought I was going to be...sniff, sniff....here I thought I would be soooo unique and write with a slinger in it.  Ohh well.   At least her character does have special powers.

         There, there, don't cry, honey.    Have you ever read "The Clan of the Cave Bear?" Actually, I've never gotten around to reading the book, but I did see the movie version at the suggestion of a female friend who is just nuts about the whole series! The main character, Ayla, is her heroine. There is a very interesting treatment of the sling in this novel. Ayla gains power and independence when she learns how to sling ( not to mention finding it easier to obtain LUNCH. ) This is a big deal as apparently the use of weapons is forbidden to women ( taboo ) in the tribe of Neanderthals who adopt Ayla when they find her as a child.                                                
         We know ( that is WE SLINGERS! know ) that the sling is a significant piece of ancient technology which dates back before recorded history and was ( and is ) widespread throughout the world.
It is puzzling and rather annoying that it has been largely ignored in both literature and film. By exploring the sling in your novel you are doing us all a service, especially for people who may have never heard of the sling but will learn about it when they read your work.         
         Also, you are to be  warmly commended for signing up with Slinging.org to learn about the sling so as to ensure technical accuracy in your work. I have seen and read stuff where it was obvious that the author(s) did not care about technical accuracy and let me tell you it is very annoying. Kudos to you for your diligence!                         
         Now, you've found " a star to steer her by," so be of stout heart and good cheer and hold course steady!                                  
                                                                                                      
         So, do you feel a bit better now?                       .......Dan

i once picked up a book that didn't look very interesting when i was bored.  in the first chapter this young girl was telling someone that she could handle the bow over her shoulder, and use a sling as well.  i stormed through that book that night and went to bed very unhappy that there was not another single reference to the sling for the rest of the book.  this was so thoroughly frusterating and you had better believe that everyone in my house knew.

but anyways, i think that it will be very nice to have  another book that talks about slinging.
