If you have the time, here are three suggestions:

Good Omens by Neil Gaiman & Terry Pratchett.  I have no idea how they worked  together, but the book reads as if Mr. Gaiman provided the plot and Mr. Pratchett did the writing, and then they went over it together.  Fans of Terry Pratchett probably know from his Discworld series that the first 10 - 20 pages are laugh-out-loud fall-down funny, and then he settles into gentle humor for the rest of the volume.  This one has the unique humor all the way through.  It has become a cult favorite.  It deserves to be. 

 What Is The Name of This Book? by Raymond Smullyan (may be out of print).  Prof. Smullyan is the best known and best creator of recreational logic problems, particularly two-sided logic, where there are liars and truth tellers.  The puzzles are delightful, and, working further into the book, baffling.  Wikipedia has some good examples under Knights and Knaves and they may serve as an introduction to the far more challenging problems in the book.  Do have a pencil and paper ready -- you'll need it.

America's Women by Gail Collins.  Ms. Collins is a columnist for the New York Times, a first rate journalist with a fine sense of humor.  This book focuses on the lives of women in the colonies and later the United States over 400 years.  The scholarship is first rate, and so is the writing. Scholarship doesn't have to be dull.  It's available in paperback and e-reader editions.
