Oh, oh, okay! The Young Wizards book are only possibly my favourite books in the universe! I don't know if they'd have quite the same impact if you don't read them when you're an awkward bookish thirteen-year-old (as the protagonist is in the first one) but essentially these books are about a bunch of smart teenagers saving the world with wizardry, which in this universe is a delicious combination of magical phenomena that has a decent grounding in physics at least some of the time, and of using words in the right way at the right time. (For instance, if you need to run from evil when it's trapped you atop a New York City skyscraper, you tell the air to remember that time when all its component pollutant minerals were in solid rock and then run away across the solidified remembrance! Or you calculate the velocities of various bodies and how much air you're going to need before you go off teleporting to the moon. &c.) And wizardry is employed, as they say, in the service of life, as a way of fighting the inevitable entropy of the universe, and ... if I was more awake I would give the premise the justice it deserves.

Just imagine that Fraser is a teenager with magical powers in the not-cheesy way and you've basically got it too, though. :D

Or, er, just take a look at the wiki page. Although, uh, I might just look at the premise blurb and then go right down to the book list, because the page is not ruin-the-books spoilery but it is spoilery.
