I was required to purchase this as part of a graduate program on cybersecurity. While I choked when I saw the price, I have found it to be both interesting and helpful. The cases which they go over at the beginning are cases that you would typically read during the first year of law school, and are presented to provide fundamental legal concepts, but the book quickly moves to cyberlaw. Some school books, I think you buy and then resell as soon as you are done; this one, I will keep and use as a reference. I like the book a lot, and recommend it with enthusiasm.
