A Single Shard has much in common with The Golden Goblet. Though the settings are very different, the main character in each story struggles to overcome unfortunate circumstances in order to pursue an art form he truly loves. Between the two, A Single Shard seems more accessible for a broader, and perhaps also slightly younger audience. Though there is hardship and sadness in A Single Shard, there is not the violence and abuse that appears in The Golden Goblet, making it a less distressing story for elementary readers. A Single Shard is also partly a road story, which will appeal to young readers' (and especially boys') sense of adventure. (Though the "road" portion of the book could have been longer. It begins more than halfway through the story, which is a long time to wait if you're hoping for action.)
The characters in A Single Shard, though few, are quite well-developed. The central friendship between Tree-ear and Crane-man provides an emotional core to the story that shapes the reader's feelings for Tree-ear and hope for his success. The slow reveal of information surrounding the tragedy that has struck Min's life is also very effective, and it enables the reader to feel Tree-ear's growing sense of affection for the potter and his wife. The kindness of the potter's wife, too, is notable, and she, of all the characters, makes an excellent role model for showing true charity to other human beings without asking for anything in return.
Interestingly, this is yet another historical fiction novel in which a character has a disability, the third I have read recently where the affliction is a deformed limb, and the second where the injury is to the foot. In Thieves of Ostia, Lupus is mute because his tongue has been cut from his mouth. In The Last Girls of Pompeii, Julia's parents want to send her away because of a withered arm. In Shadow Spinner, Marjan has a crippled foot that limits her ability to marry or find work. While I wonder how prevalent these conditions actually were during the time periods represented by these books, I do think it is interesting that the authors chose to include them, and to portray the ways these characters were ostracized and stigmatized for being different. For elementary and middle school kids, these characters present opportunities to consider the injustices imposed by different societies and to think about how our current culture's treatment of the disabled is the same or different.
Included as a preface in my copy of this book is Linda Sue Park's Newbery Medal acceptance speech. In it, she explains the inspiration for the book - a real piece of pottery from this time period which is decorated with cranes. For kids who feel that historical fiction is too far removed from real life, or who have a hard time connecting to books set in the distant past, having this connection to a real object might help them engage more with a story they would otherwise ignore. I also think that writing the backstory for a real object - historical or not - is a great exercise and a perfect writing assignment to accompany a literature study of this book.
A Single Shard is a powerful, emotional, and exciting read about a time period and setting not often represented in children's fiction. It makes an excellent complement to a study on Korean history, especially thanks to the historical details given in the author's note, but it works just as well as a novel to read for enjoyment.
