" I am starting to get a little frustrated by this series. Each book is about one clue, but (I'm guessing that) because some clues are available through card packs and website, there is no attempt to summarize clues to date and as a result it's becoming a little frustrating. Do the clues add up to anything yet? Am I supposed to be keeping track of them myself. I've read all the books in the series to date, but have no idea what kind of progress we've made. I'll stick with it, but with less enthusiasm... "
