I love sci-fi type of reading...(not as extreme as the Yeast Wars ; The Bronco Years
One series I fell in love with from the 'young adult' reading section.
"The Bartimaeus Trilogy."
I flew threw the series in no time flat, laughed and was kept bay and then cried (a little) and then went..."Phew there should be a 4th 5th 6th book!!!"
Anyway for what it is worth, it is good reading. Regarding Magicians in modern day England that have supreme powers carried on from the master magicians of old, not the play of hand magic tricks, those are amatuers....
Anyway each of these magicians can conjure up demons of various degree depending on their particular skills, etc. its a story that follows a young magician apprentice.
