Best book for Quantum mechanics

[SUROJL]

Hi everyone,
I am looking for a book on Quantum mechanics(or physics book of higher level)...the book shouldn't be too complex( I know higher level physics is really hard ... I heard). I am college sophomore chemical engineering student. I have taken general physics and general chemistry classes. I was actually in Physics major before but later I decided to study Physics on my own. Most of time I understand the contents to book if it have short and conceptual explanation and mathematical relationship. Anybody know book I can start reading to that I would actually know some Physics? Thnks everyone.

Of course there are lots of them, but from a pedagogical point, Morrisons "Understanding quantum physics - a user's manual" is really good.
