Really Really Liking a Book

When can u say u really really liked a book?

Here is my definition.

You buy a book thinking it will be good.
You start with it and voraciously read it day and night to reach the end as fast as u can. Then u keep it aside.
After few days u feel like reading it again. U tell urself that I will not take long time this time. I will just read out the parts I liked most.
But surprisingly u find urself reading each and every line. Very slowly in laid back attitude. U want to read each and every detail savor it. And u take long long time to finish it up this time.

Ah yeah, then u know u really really liked the book!!
