Didn't grab me. Seemed like Harry Potter for teenagers -- wish fulfillment that you're really, really smart, you'll be whisked off to study magic, and then get to go the planet from your favorite fantasy novel. Wee!

The prose is a bit clunky in places. Perhaps it lacked copy editing? In the sample of the next book that was at the end, Eliot's stallion rears up, and "hooves" the air. Earlier in the novel, Quentin calls Alice "Vix", and then there are some sentences explaining that he's using a nickname, short for vixen, which is a female fox, and so on. Then he never uses the nickname again. Either don't use a nickname, or use "Vixen" and don't explain it because the reader should easily figure that out.
