this is a pretty long question so i put all of it in the details part

ok so ever since rise of the ogre came out iv been busting my butt trying to find it, but the book stores in my area rnt in alphabetical ordr so i wud have 2 find it par genre, thing is im not 100% sure of what the genre is so i have to ask the people @ the store if they have. naturally they give me a puzzled look when i ask if they have a book calld rise of the ogre nd say no i dnt think so nd walk away without even looking. nd the librarys dnt have the book eithr, whenever i do get my hands on the book tho its $15-$20 nd i dnt wanna pay that much 4 a book i can easily read in one sitting :/ so here r my 2 questions:
1. what is the genre of the book, im thinking eithr music, musical biographies, biographies, ficiton, ou fictional biographies
2.will the book get any cheaper than $15-$20? btw thx 4 ur help nd answers!!! nd also thx 4 going thru lire this long question ^_^
