I've been a fan of this author's work since I read the first edition of his Buffy the Vampire Slayer guide, Slayer, two years ago. I really like what Topping has done with the dull and dry world of the episode guide book. There is really nothing more boring that getting a book (usually "official") on a series which includes a ten line plot description, a couple of fuzzy off-set photos, a few inane 'Did You Know' things and an interview with the set designer. That doesn't, actually, tell the reader any reason why they are fans of the show that they're reading about - about all of the great lines of dialogue, the set-pieces, the funny bits. Now, I'll be honest with you, I've never been a huge fan of Stargate SG-1. I like the series, sure, but it's not one that I've ever watched with anything like the devotion that such a book as this would require. But, I'm think of becoming one right now because the enthusiasm with which Keith writes is utterly infectious. So, highly recommended to fans of Stargate, of Topping's previous work, and of anybody who wants to know how an episode guide to a television series should be written. Very good indeed.
