This book is very well written with lots of examples and plenty of formulae and problems to practice. It starts with the basics of MOSFETs, talks a little bit about Mask Design, and then moves on to IV Characteristics, pass transistors, logic gates, transmission gates, and so on. It is a fantastic book to understand how logic circuits behave and to use a reference for basic spice circuit analysis.
If there is one thing I should complain about, it is that the psychedelic color on the cover gives the illusion that the subject is scarier than it actually is. :-)
