The topics are clearly explained at a leisurely pace, and I enjoyed the frequent, well thought out exercises. This is the rare mathematics textbook that includes answers to all the exercises, instead of, say, leaving you scratching your head for a month before you figure out you're chasing a careless typo.
One quibble: so many combinatorics problems are posed along the lines of "match up every girl with every boy" etc. and it's like, it's the 21st century, can we just, y'know, not?
