This book was very well written. I mean, I barely found any typos. :) 
 This book is the first in a series called "The Seven Realms". I liked the plot in the book. Usually I can predict what the author will do, but this time...NOPE. It had me second guessing everything. I did assume something was up with Han, but I didn't know what. Raisa was a good character, and not because she is a princess ;) It takes place in more than one place.. There are cites like Ragmarket and gangs called the Southies and Raggers. Lands called Arden, Vale, and Fells. 
 This book compared another I've recently, called, "Science Fair". I think this book has a better plot and better characters. It had something of a love triangle and romance that "Science Fair" didn't and doesn't have. It has adventure, comedy, and things that had me laughing, even though the situation was sort of...bad. Oops, actually, nah. It made me laugh, so what. 
 There are, actually, something of two main plots, because the book has two main characters; Han and Raisa. The plot Han is in is; Why do the Bayars have the amulet that belonged the the Demon King? Raisa's, amazingly, also involves the Bayars; What is going on in the castle and how are the Bayars connected? 
 I will be reading the second book very soon(Try today :P) and I can' wait! I'm expecting Han and Raisa to meet again. Haha, hope Amon don't get too jealous. ;)
