I started buying ilex published books about a year ago with Michael Freeman's excellent guides on photography. As a relative beginner I was very impressed with how he discusses the craft and have bought almost all of his books since then.
As for this, I would say that it is not written quite as well as Michael Freeman's books but still very useful if you are looking to take the step into Wedding photography. Ilex seem to be extremely talented when it comes to choosing the best people to discuss photography and film and I would happily recommend any of their range to anyone who wants to challenge what they think they know about photography and really analyse their own skills.
