I have half read Six of Crows and now in love with that book. Harry Potter is for kids which are younger than kids reading Six of Crows. I just love every aspect of the book. From the dialogues to the plot. It is filled with every emotions - Action , Love , Humour , Sadness, Horrer, Violence, Happiness , Suspense, etc. Each character 's background is described in detail. Every Chapter has an ending which will urge you to read more.
