Fish in a tree / Lynda Mullaly Hunt.

"Ally has been smart enough to fool a lot of smart people. Every time she lands in a new school, she is able to hide her inability to read by creating clever yet disruptive distractions. She is afraid to ask for help; after all, how can you cure dumb? However, Ally's newest teacher sees the bright, creative kid underneath the troublemaker and helps to shine a light on her gifts. As her confidence grows, Ally feels free to be herself and gets to know other kids who break the mould. When the outsiders start to fit in, suprising things begin to happen in Ally's classroom that show her there's a lot more to her - and to everyone - than a label."--Provided by publisher.
