There aren't enough children's writers on this site. I would love to give some shelf room to some great Children's and/or Middle Grade books. Not YA(sorry!). So if any one has any suggestions please post them below. Here are a few of my favorites:
1. My Friends Are Dead People by Tony O. (MG Story)- http://www.authonomy.com/books/36573/my-friends-are-dead-people/
"A black cat. Zombies. Witches. Werewolves. And an afterlife that has turned some of the dead into monsters."
2. The Silhouette by Thomas Shaw. (MG Story)- http://www.authonomy.com/books/34102/the-silhouette-alan-quinn-1-/
"When his father goes missing, Alan Quinn’s search plunges him straight into the middle of an ongoing battle of magical races."
3. Magic of the Frogs by JJ(Children's)- http://www.authonomy.com/books/33971/magic-of-the-frogs/
"What do a dark wizard and a beautiful sprite have in common?They are both searching for Bastion, and the Frogs of Covington." 
Here's one for the New Year.
Power Puppy by Michelle Williamson
Adventure, excitement, it has it all. Probably for 8 - 12 year-olds depending on reading ability.
