Ooooh, I love a good mystery, and this one was a fantastic one! It was SO different from Rosanne Parry's Heart of a Shepherd, but I loved it just as much. It's set in Germany at the time the Berlin Wall came down, and although the main characters are girls, there's plenty for boys to love, too. For starters, a soldier gets thrown off a bridge and left to die! Then there's the sneaking off to Paris. And the four of them trying to escape a scary guy on a train. And on and on.
It is a great book that kept me up reading way past my bedtime for several nights in a row! I highly recommend this novel to all lovers of action, adventure and mystery. Additionally, there's a big musical component in this novel, as the girls are in a classical music trio, so if you like music you'd probably enjoy this story, too.
