Critiquing Time

So...I'm finally on to the next step of my new, young adult, historical fiction chapter book, "Sarah's Storm." As I push through this week to finish the ending of my story and manuscript, I am editing and sending out my first few chapters to two young ladies to critique. I'm a little nervous about the feedback they will give me but am excited to go to the "next level" of the book. I have chosen two teenagers who are well read and write well to do my first critiques since young adults are my target audience. Then I will make a few adjustments (I'm sure) and hand it over to an adult to critique, then after a few more adjustments (again, I'm sure) it will be off to my editor. Whew....
