A silly fairy-tale for the 'tween-age kids

My name is Mark Simon Smith and I've self-published an e-book called Sir Nathan and the Quest for Queen Gobbledeegook. 

I originally wrote the story just for fun about 9 years ago for my younger nieces and nephews, but now that my son is 9 years old, I've dusted the work off and re-edited for general release.  It's a silly fantasy story about a over-exuberant knight who must find his missing queen.  Along the way he runs into pixies and wizards and other bizarre characters in extraordinary lands.  The work is written in such a way that it hopefully appeals not only to the young, but the young at heart as well.  My dream is to create works that parents enjoy reading with their kids.  Early responses from readers have been positive and encouraging.

The book is currently available on Amazon.com and Barnes and Noble as well as Smashwords.  I'm about a week away from having it available as a print-on-demand book through Amazon's CreateSpace.

It's been interesting dipping my toes into the waters of self-publication.  Here I thought writing and editing the book was difficult, but turns out the marketing side is a whole other beast unto itself.  And, strangely enough, I'm not running into that many other self-published works for the age range of around 8 to 12.  I see the Young Adult writers out there and the young children authors, but not so many in this in-between range.  I'm interested in speaking with other authors about their trials and tribulations in the self-publishing world, as well as other authors writing for the same age range that I am.  

Also, since what writer isn't first and foremost a voracious reader, I'm looking to help other authors in what ways I can through cross-marketing and other ways.

thanks!
