Comparisons?

When I look at the two books I am currently reading, Much Ado About Nothing and Failure is Not an Option, I do not see many similarities between the two. Much Ado is a love story and, as the title reveals, really should not be taken seriously by the reader. It is apparent that Shakespeare did not intend to make this a story that people are affected by, but the book is still interesting and fun to read. Failure, on the other hand, is a nonfiction book that gives you insight on the evolution of the space program and also teaches the reading about many themes that they can use throughout their life.
