The third Darth Bane book overall does not disappoint. Unlike the first two books however, I felt it had a rather slowish start. The book opens with little in the way of action - something we saw so much of in the previous books. There is a 'shoot out' here and there, but the beginning mostly introduces you to various new characters (and forgotten old ones) as well as what is going on inside their minds. This can be interesting at times, but I felt that overall in terms of entertainment value the opening quarter of the book was a little hit and miss.
Once this book got going however, it was as exciting as anything we've seen in the previous two novels. All the individual narratives merge into one making it nearly impossible to put this book down (much like the other Darth Bane books).
My only other complaint is the final paragraph of the book (excluding the epilogue) which was frustratingly confusing. When you get there you'll understand what I mean - the good news however, is that the author clears this up on his website.
To conclude, I'm pleased to say this novel is a worthy conclusion to the Darth Bane trilogy. Apart from the slowish start and slightly confusing ending it is a thoroughly enjoyable read. If you've read the other Darth Bane books and are heisting buying this book please do so no longer. I'm sure you won't be disappointed.
I would also urge any Star Wars (or sci-fi) fan who has not read the Bane trilogy to do so. It's surely the finest trilogy of Star Wars books.
If you want a comparison against the other Bane books I would rank this book overall the weakest of the trilogy (with the first being the strongest book). However, this does not mean it's a bad book, I still really enjoyed it...and I'm sure you will too.
