MG vs. YA?

The authors at MiG Writers recently shared a FANTASTIC post about the difference between MG (Mid-grade) and YA (Young Adult) fiction: MG vs YA fiction: What's the Difference?
     It includes this funny cartoon by Debbie Ohi. Remember Debbie? She did that awesome comic strip of me during my Soap, Soap, Soap blog tour?
     So, if you ever wondered what age range your novel falls into - maybe you'll find an answer there!
