"The Rithmatist" by Brandon Sanderson

This book for young adults was an enjoyable read, though the idea of 2 dimensional chalk figures is a bit out there. The book ended leaving many interesting questions unanswered, but I won't go out of my way waiting for the next volume to be published. When I was reading it, there were definitely times when I felt that this was a book for young adults i.e. an element of preachiness.. whereas I think a truly well written story in this genre should just be a story, and any preachiness should feel more natural.
