Okay, seriously. The only gaming book I'm aware that this guy's ever written was the Halo 1 adaptation. It was full of inaccuracies, out of character behaviour and generally showed a lack of understanding of the universe it was written in. It was the only truly bad Halo book, and he was never invited back to write another. Knowing that, I was wary of this book going in, but, I was determined to give it a fair shake.
Unfortunately, Dietz has shown the same casual disregard for the Mass Effect universe as he did for Halo. For a start, you should read this: [...] A document which, at current count, contains 48 fairly large inaccuracies for a man who claims to have read the three preceeding books. He skimmed them, at best.
But even disregarding that, if I were rating this story based on it's own merit? It's still terrible. Even if you have no experience of Mass Effect at all, and the issues I've mentioned so far mean nothing to you, you still shouldn't read this book. The plot is choppy, with little real direction or focus. Characters are handled poorly, with odd, unrealistic reactions to situations. A main character meets a girl, who looks upon him with "undeserved devotion". Next time we see them from a distance, they're holding hands, we assume they're suddenly boyfriend and girlfriend. The time after that, a random guard gets shot dead, and apparently it was the girl and "they were in love and about to be married". I might care about that or even believe it if she'd had more than 2 lines of dialogue, or more than a few fleeting non-speaking appearances. Another girl finds herself in possession of a secret message encoded into her necklace, containing holo footage of an event that occurred years after the necklace was given to her. One character, Mythra Zon, is routinely incorrectly referred to as Von. Sometimes both Zon and Von occur on the same page, within lines of each other. Another Mass Effect character, Barla Von, is given a brief cameo mention early in the book, so it might confuse you when "Von" starts showing up later in the book.
And that's just a few examples. A fairly important main character to the franchise, suddenly had an entire family invented for her. Even though we know her entire identity is fake. Apparently Dietz didn't. I realise this review is a little all over the place, but let's be honest, no one but Mass Effect fans are going to read it anyway. Trust me, this book is rubbish. Buy it if you're really curious. Don't buy it if you expect a good read, or if you expect to be happy with what he does with characters you might've enjoyed in previous books.
