The Temp is a very compelling and enjoyable read. I am a veteran Wall Street/City banker (male), and find the author's characterisations of office life spot on. Anyone who has been an employee can relate to her clever observations (which you can only assume are based on some crazy real-life experiences!). Half the time you laugh out loud at how dumb people can be, and the other half you are outraged at their bad behaviour.
That said, the book is about much more than office life and temping. What hit home most was the theme of leaving university and heading out into real life in the big city. Seeing your friends (and yourself) change and adapt is not an easy experience. You find that some people were friends only because you lived with or near them, and they drift away, back into the world from which they came. Others define themselves and those around them by their jobs and relative success, and end and lose friendships because of this. You learn that the people that you really like, have something in common with, and are loyal - no matter what or how well you do - are absolute gold.
The book's short chapters race along, and there's never a dull moment. The characters are interesting, varied, and well developed.
