The Troubletwisters #3: The Mystery by Garth Nix and Sean Williams

This book is the third in the series, with a 2013 copyright, and I gave it a rating of four out of five. Grandma X is in the hospital, because someone tried to kill her by running her car off the road. Also, a well-known citizen of Portland dies mysteriously, and there is a great deal of interest in his castle. The father of Jaide and Jack tells them that they must find a golden card hidden there to help the Wardens fight off The Evil. He's behaving strangely, and he insists that the twins must get the card immediately. A pet macaw, the only witness to the citizen's mysterious death, blurts out strange words and phrases, and it freaks out when it sees a picture of the twins' father. Is their father being controlled by The Evil? The twins are once again left on their own to make sense of the confusion and save the world.

Although I've given all three books the same rating, I enjoyed this one the most. The mystery was more obvious in this book, and there were many clues shared to help in solving it. The adventure was complicated, because readers are told that one of the characters, someone seemingly innocent, is actually evil. This fact kept the twins and me wondering who to trust. The plot built up to an exciting climax and left me wondering, and looking forward to, the fourth book.
