Query: A Word of Warning and Clarification

Most of the reviews of and comments about "The Magician Trilogy" mention "Harry Potter", (because, well, it's "Harry Potter"), and the Charlie Bone series, (because it's also by Nimmo and it's very much like Potter). Be warned that "The Magician Trilogy" is not anything like those other two sets.There is no wizarding world, there is no "magic system", there are no spells or incantations. In this series there may be old magic in the hills, and in the memory; there may be mystery in the bones of the earth or the bright eyes of unusual birds; the fog may bring passing enchantment with it on particular nights; but this is not wand waving magic.These books are moody, indirect and ambiguous, like the old tales themselves. That's certainly not a bad thing, but I would hate to have someone disappointed by this wonderful series because they expected Hogwarts magic and cleverness.
