X-Men Dark Mirror is a very enjoyable read that keeps you interested and wondering all the time. However, this book is not to everyone's taste, you will either dislike it or enjoy it but it is not for the faint hearted and at times, has some strong language and violence that is strictly for adults eyes only or older teenagers. The book is not at all like the comic books. It is not explosive, action packed and predictable but focuses more on how the five X-Men (Logan, Scott, Jean, Rogue and Nightcrawler) cope with their issues of being in somebody else's body. It is well written but at times, the American grammar can be confusing. It sometimes feels as if the writer tries too hard to describe certain situations, thrust making it hard to visualise the scene clearly. There is some humour, particularly from new-lady Logan but the book is mostly serious and switches from between the X-Men and the other X-Men at the mansion (Gambit, Jubilee and Storm) and how they come to realize that the impostors are not who they say they are. The villain (whom did not seem very powerful compared to others) was good but not great. It was only nearing the end of the book that we learn his full history but hey, the book keeps you guessing! Surprisingly, there are hardly any cheesy lines but I must warn you, the final battle was very confusing, I had to read it twice but otherwise it is well written and a very good read.
I recommend this book but not for young X-Men fans! 4/5.
