I was intrigued by this little book of psychology when I picked it up in a used bookstore. While it offers brief overviews of each of the major areas of psychology (cognitive, personality, behavioral, trauma, sleep, etc.), I found it to be a rather insipid read; it wasn't nearly as exploratory as I would've liked. This is probably because the author tries a bit too hard to make the book as "readable" as possible, and frequently dumbs down the information/research to make the information more palatable to the average reader.
For those looking for a comprehensive, well-rounded presentation of the multiple areas of psychology, this is probably not the book for you. However, if you're interested in some light reading that briefly touches on multiple areas of psychological study, you might enjoy this one.
