Update: Much better! Thanks for fleshing it out. My original reply is preserved below, but it is no longer applicable as far as I'm concerned. (Original reply follows.)
Sorry, but I felt I had to downvote this. You've given us a short statement about your opinion of the book. Fine. But you haven't really reviewed it for us. The closest you came to reviewing it was calling it "concise and easy to read". Beyond that, it comes across as a marketing blurb. How has the book been helpful to you? Is it missing anything relevant or is it truly comprehensive? Does it focus on high-level testing issues or low-level details or is there a mix of both? What can you tell us about the book other than that you like it?
