This is probably my least favorite book in the series so far.
Let me state first that I'm most likely not the target audience, as I'm twice as old as Augum. That means that I don't have a lot of patience for the teenage drama that takes place in this book, and that's the biggest contributor to my rating of 2 stars.
Aside from that, the pacing felt off, and the simultaneous quests of the tournament and the library made the entire storyline too strained and too unnatural. Too much needed to happen in order to pull the ending off.
The final battle also felt extremely rushed, convoluted and confusing, and I can't say any more about it without having to use spoiler tags and I hate those, so I won't.
Again there were quite some grammar issues (then/than, all right vs alright, some weirdly constructed sentences) and if we're nitpicking: what bothered me immensely was that apparently in Sithesia there is such a thing as acidic soap. Soap in the actual world is made of lye and fat, and lye is the exact OPPOSITE from acid, it's alkaline! It's the opposite end of the pH spectrum! Soap will therefor never taste acidic, for there are NO acids in soap!
That being said, I've come until book 4 now and I'm not going to stop until I've finished the series. Legend better be living up to its name!
