Coates give comfort and aid to everyone who has ever wished they were more knowledgeable about Shakespeare but can’t find the time to dig in. In addition to summarizing each play in one sentence, the coauthors provide historical context for Shakespeare’s literary output, including his sonnets, and most famous speeches.
