Query: TRUST ME! very good textbook, no mysteries here.

This is a very good textbook. Good explanations. Clear, yet challenging. For serious CS people. Otherwise, don't bother. Leaves reader with clear understanding of the subject. More than ample examples and problems. Even semi-satisfactory studying arms reader with an advantage when it comes to exam content because the book problems resemble those of test problems. Solutions manual is a must.
