I like it!
Hey, I just bought that book a few days ago. I haven't had time to read it all but from what I've read, it is a great manual for the DAW! It's also a great reference book for whenever you're trying to do something but you're not quite sure what to click on or which option to choose. I personally like the book and if you're just starting out with Sonar I would highly recommend it so you can find yourself around the GUI.
