The second instalment in the Magic Crystals series, immediately following the events of 'The Seventh Sorcerer'.The original villain is back, only this time he is on a different mission, taking orders from the evil and cunning Hammerson Sorcerers, and his path will intersect those of John Playman and his friends on Rock Haulter.A desperate race must ensue, Moran and the powers of the Hammersons against the Chopville teens. The prize will be the most powerful of all the Magic Crystals and a control over the balance of life, but such extraordinary power is heavily protected. There is no guarantee that all will live to see the end.The danger faced this week will be greater than anything faced in 'The Seventh Sorcerer', but that won't stop the teens from having a good time, as only teenagers can. But beneath all that, a far more serious situation is simmering.It is only those closest to the Sorcerers who understand how delicate the peace between the Woodwards and Hammersons is, and how quickly that could change.
