Book excerpt: When Tyler and his family are putting up the Christmas decorations, Tyler takes a look at the Christmas-tree angel, and asks, “Why are they always pink? Aren't there any black angels?” It's a question that no one can answer - not even his friend, Carl. And when Tyler starts combing the shops for a black angel, there are none to be found. But, late on Christmas Day, a surprise delivery from Santa convinces Tyler that there are angels just like him.
