...The Darksword Trilogy, as a whole, is an intruiging series. I always liked Saryon- he's just so kind and lovable. My absolute favorite character is Simkin, of course. Simkin represents the joker in all of us, and I laughed so hard I cried at some of his tricks. Joram is the exact opposite- he's the dark side in all of us, eager to find the light. I was always kind of hoping he would realize what a jerk he was being, but by the end of the first book I realized that wasn't going to happen, and it turned out for the better, apparently, in "Doom of the Darksword." Mosiah is most of us- trying (unsuccessfully) to get our friends to realize how hardheaded they're being and being quite helpful to others anyway. Other characters flit in and out of the novels (Blachloch, Elspeth, Anja) but the ones that last for a while are very good.
Okay. "Triumph of the Darksword" is a Five because of its flipping back and forth. You like Major Boris because he represents the good military man we know, but on the side of Thimhallan, who you've been following since the beginning, he and Menju represent everything evil to them- Technologists, Dead people who use the old art of Technology to destroy and annex and basically do bad things. The characters in this novel were as true to form as ever, and fit their molds in the Prophecy as expected (though I was a little put out at what happens to Simkin) and the plot is pretty good, as far as fantasy goes.
Personally, I liked the second book of the trilogy best, as far as character actions went. But for the plot and results of the entire trilogy- this one was the best. Read it and you'll fall in love.
