Borrowed this and another book from the Library. The Explanations were too long, too long winded and full of hyperbole. It missed out vital information in the explanations such as how to actually find the healing tool. Since I had moved up from PS6 it was a vital piece of information for me.
Gave up trying to follow it and added Scott Kilby's book to my shopping basket instead. Not as in depth but easier to follow and it covers what I want to know.
