I don't even know what to say about this book. The illustrations are great but I don't know what the story is supposed to imply. I say imply because it's one of those wordless books. I'm cool with wordless book but I have know idea where this was supposed to lead. 
 Bullied boy has no friends. Boy meets bluebird. They have a great day and become besties. They go to the lake and sail boats with other kids. That's the part where I thought the boy made friends. Thanks bird. End of story. Nope. Boy heads home and is ambushed by bullies. They fight. Bluebird gets involved like any good bluebird friend would and is hit with a stick. Said injury is fatal. Yes fatal I say! Boy is carried off by a rainbow of birds and releases bluebird into the heaven which can also be misconstrued as the sky in which case maybe he was just hurt and not dead but I don't think so. 
 This book could be about anything in the end. Just picture me with a puzzled look on my face and my hands raised like whaaaaat!
