Young Authors/The Mirror That Didn't Reflect

I just finished writing my Young Authors story for this year! It is called The Mirror That Didn't Reflect.Here is a summary of it. Tim, Susie's brother, has left for Boy Scout Camp. After walking past the bathroom mirror, Susie realizes that she doesn't see herself! She goes to her friend Madison's house, and Madison comes over. They talk about it with Susie's mom, and solve the mystery of why the mirror didn't reflect! The "mirror" is a painting, with Tim's initials, T.Z.B.! When Tim gets home, he gets in trouble! This is just a summary, and it takes the real book to understand and like the story. I got complements such as "It makes them want to read on" and "The communication is believable". [like 5 kids wanted to read it to them selves!!]
