A while back, I reviewed The Shifter a YA Fantasy by Janice Hardy, and now, there's a contest on Janice's blog to win the ARC of the sequel, Blue Fire, which comes out October 5.
Here's the link to the contest: http://storyflip.blogspot.com/2010/07/light-my-blue-fire-contest.html">
Aside from a fast-moving plot, and good worldbuilding, The Shifter is clean. No cussin'. Highly recommend for Middle Graders.
Also, Janice has great info on her site like Real Life Diagnostics and How to Write a Query and When Plots Go Astray.
