Hello, boys and girls! I have just read a great YA fantasy called "A School for Sorcery" by E. Rose Sabin. I loved it! A lot of fantasy has lots of walking around and talking, or 'world-building', and then kind of skips through the magic really fast. "And then she did a spell"-type of thing, but without telling you the spell. This one was very different. It was quite rich with a very fascinating magical system, along with discussions about the ethics of using certain types of magic, and the price one had to pay. For instance, if you alter time, you alter the balance, and you have to make it up one day. It was fascinating!
Also good: Martha Wells' "Fall of Ile-Rien" trilogy. I thought the first one was a little slow, but by the middle of book two I was hooked hard!
