This is a wonderful book. The plot is strong, the characters are true, the political intrigue is mysterious and gut twisting (without being dwelled upon too long so as to make it boring), the action is intensely breath-stealing and everyone's emotions are beautifully handled. The author avoids a common pitfall of TV tie-in books by not relying on the reader's interest in reading about their favorite characters as a substitute to developing a truly engrossing plot. The unfolding chain of events dominos quickly from its simple and familiar beginnings - a wish to bring lost comrades home, some stubborn, deceptive aliens and the ever pervasive threat of the political factions aligned against the SGC - into an adventure full of danger and surprises. The action scenes were particularly well written and had me on the edge of my seat repeatedly. I liked the way that every time you thought you knew what was going to happen or that they were finally going to make it into the clear, some new turn would be thrown into the works. Excellent! Everyone's emotions were also very well done and true to character. The way the author got into their heads and showed their interactions and the cause and effect of events was wonderful to read. Some parts I've already read multiple times just because they are so well done. It's like watching the show, only better in some ways because you can get what people are thinking, not just what they say and do.
I highly recommend this book, it is definitively a gripping page-turner!
