Sweet Reason: A Field Guide to Modern Logic

If you want a boring book that tells you exactly what to do to get a good grade from your teacher, this is not it. If you want an interesting book that gets to the heart of modern logic with a rich collection of examples in real real life (as opposed to fake real life) ranging from politics to Donald Duck comics, that encourage you to think for yourself (sadly, no-one can make you think for yourself), that gives you a sense of why people care about the subject and why you should too --- this is that book. I cannot praise it highly enough.

If your class requires this book...drop it and take something else. The textbook is written to be clever and funny instead of instructional and is by far the worst textbook I have ever used. That being said, the seller shipped very fast and the book was in great condition. It's not their fault the book authors are clearly sadistic.
