Query: captivating

I found the book very interesting, it kept me reading. I finished the book in three days, because I was always left anticipating the next scene. I must say the ending also threw me for a loop, but I was a little disappointed because I was looking for a little more detail in the conclusion. It seems that it was rushed, unless, we should expect a sequel. Overall, I was very quite pleased.
