Bechdel is truly a master at conveying a story through comics. Witty, emphatic, moving... she punches all the right buttons.
This collection aggregates the most significant portions of the major story arcs throughout the past 25 years of the strip. Though it's sad to me that anything was left out, the remaining material reads smoothly.
A great place to begin, if you're new to DTWOF, and a great place to reminisce if you're not.
