David King at Books and Things just finished reading Invisible Dawn and had the same problem classifying it that I did. His review is thorough and detailed. I highly respect Mr. King for giving me so much to think about, appreciate the time he took to read it, and am happy that he found it to be an entertaining book and series he looks forward to reading more of. Check it out and see if you agree. Also, he has great comments about other books you might be interested in picking up. I highly recommend following his blog.
