On her blog Literary Rambles, Casey has posted a Tuesday Tip I wrote about checking for character plot holes. Check it out!
Also, if you're not already familiar with Casey's blog, just check it out in general! Literary Rambles provides an amazing service to the children's writing community. Besides her Tuesday Tips, she has query and synopsis critiques, writers searching for critique partners, various interviews and tips, and the most well-researched agent spotlights you'll find on the net. Her blog's been invaluable to me as I'm getting ready to query Project Sparkle.
