Great read and a good book. Lots of topics and a refreshing look on QFT. Highly recommend it.
One caveat: you cannot learn QFT from this book. It simply does not dive into any details of the calculations. It's great as a supplement, but keep in mind that no course on QFT will ever use this book as the main text - it's too superficial for that. If you are serious about learning QFT, then go with for instance Ryder (as a first read) or Peskin and Schroeder (more advanced).
