This is the second series I have read by Tony Abbott. The first, The Haunting of Derek Stone, was amazing. I loved it, so when this new series was starting I had to read it. I was not disappointed. Tony Abbot has come up with yet another great concept and is bringing it to life for readers both young and young at heart. With a mix of Greek, Norse, Egyptian and Babylonian mythologies, a group of fourth graders, and the whole world at stake, what could go wrong? Owen Brown is in the fourth grade. One morning at school he sees the floor open up and swallow his best friend Dana Runson. This event is also witnessed by Sydney Lambertti, the new shop teacher's daughter. And the final member of our group of youngsters is Dana's and Owen's friend, Jon Doyle. After Dana's disappearance, Owen and the other two must figure out what is going on. They soon have encounters with a fire-breathing giant wolf, the lyre of Orpheus, and the three Valkyries. And that is just the beginning of the story. This first book in a new series was a delight to read. It has a fast pace, interesting characters and a wonderful plot. I cannot wait to see how the series progresses. I can highly recommend this book.
