I ended up disappointed with this book. While the main plotline was an intriguing fairy tale (Church cardinal longs for a child but obviously can't have one, so he has a 'nephew' created of glass. The glass boy falls in love with a flesh-and-blood girl, and they struggle to find a way to be together.) the execution was atrocious. The author's writing style seems very derivitive of Nathaniel Hawthorne.
