The third instalment in the Magic Crystals series, following the events of ‘The Seventh Sorcerer’ and ‘Rock Haulter’. With great power may come great responsibility, but in the case of our heroic Chopville teens, it also comes with a great big target. As they are to discover, having the Magic Crystals does not ensure their safety-in fact, quite the opposite. A dark force is gathering around Chopville, far more dangerous than Moran could have ever been. A dangerous enemy will show his murderous hand early on; a trusted ally will defect to the dark side; and John and some of his friends will be taken captive and subjected to unspeakable horrors. And through all of it, a great mystery looms darkly over John, which he must solve in order to have any hope of staying alive.
