First, for everyone who saw the tag "fantasy" and went "ewwww, elves" sit yer butt back down. This is not that type of fantasy fiction. You people and your silly boxes. *shakes head* This is more closely related to "Urban Fantasy" but even that isn't bang on. What we have here is an interesting little hybrid of UF, Historical Fiction, Romance... oh hell, just go get this one and read it. 
 The plot pits two young magicians against each other in competition, basically Art versus Science. The rules haven't been explained to either of them. Indeed, they aren't even told who their opponent is. Our setting is the Circus, and the goal is merely to win. Sounds simple, doesn't it? Too simple. It's always easiest to get lost where there arent any landmarks. 
 The descriptions are lush without going overboard. The author leaves just enough room in them to let your mind conjure the images to suit your own tastes. We're paced at a slow stroll, giving us all the time needed to look around, imagine, and admire the settings, and believe me, you'll want to. However, it may turn off folks who prefer to see a lot of plot pushed, young adult readers may find it drags for them. 
 Special thanks to my cousin (who's name i wont use as I dont know her preferences in these things) for recommending this one to me.
