Really enjoyable. YA novel about intrigue and danger. Plus there are secret passages, and people doing bad things for personal reasons that make sense, and danger. I loved this world and the characters are strong. It's fun and light. And watching Digger grow from a mistrustful thief with so much to hide to a person who really cares about the people around her was a great part of the book, and done believably.
My only complaint is that in the kindle edition that I read there were formatting errors. Words were often formated with a space in between syllables. It was very distracting, but as it isn't the fault of the author, I cannot hold it against the book. Just a warning to future readers, you might want to try another edition of the book.
