If youre already a fan of Diana Wynne Jones, you know that any book written by this amazing author is worth reading. The lives of Christopher Chant is no exception. Quite possibly it is one of her best works, but I'll let you decide on that one. This particular book actually takes place before any of the others, but for some reason it is the fourth in the series. It stars a young chrestomanci - Christopher Chant - a boy who can traverse through the multiple worlds at will, who unknowingly posesses nine lives and is one of the strongest magic -users in his own world. He is taken to Chrestomanci castle, where he is trained to become the next Chrestomanci, a sort of overseer for all the magic that goes on in the many worlds. However, he is also secretly recruited by his uncle Ralph to make a series of dreamlike trips into the other worlds to retrieve and deliver mysterious packages, one of which is incidently revealed to be dragon's blood, a highly powerful and illegal magical ingredient prohibited by the law. Christopher is exposed to countless dangers on these forays and each time he dies in his spirit trips, he is killed in the real world by a parallel accident. As time passes and Christopher continues to lose his lives, the reigning Chrestomanci is killed and the worlds are pushed into chaos. Christopher, young as he is, must take charge and save the entire related worlds, though he is only just beginning to discover the scope of his powers... enjoy!
