"The Darksteel Eye" was a fairly one dimensional book. There is not very much too it, except for basically rehashing the first book in the cycle, "The Moons of Mirrodin." Running away from the enemies, searching for items that are in places the characters have already been, except they wern't "ready" to understand the items use, or "wouldn't believe it."
This book has a severe time disorientation. It is so hard to follow time because it will take many chapters for the characters to go from, say, the plains to the swamp, while then it takes them only a chapter break to go from the center of Mirrodin to the forests on the surface. It seems the Mirrodin block is all about visiting the five mana sources (plains, swamp, islands, mountains, and forests) because in everybook they somehow, for some reason, need to run to all of them, and fight the same creatures in all of them. There is always, ALWAYS, fighting going on, and it gets very old because the fights are not that engaging.
However, despite the one dimensional characters and plot, there is one moment in the book that I felt some serious emotion for the "bad guy." I really felt for him, and had a lot of empathy for him. It was an extremely sad part, for me.
They also find an item that wasn't even in the cardset for "Darksteel." This item didn't come out on card until the next set, "A Fifth Dawn."
Despite the flaws in this book, I am still going to read the next book because I am interested in the final interaction between the heroes and Memnarch, and then, as the back of the book states, the planeswalker Karn, who created Mirrodin. Hopefully it won't be a lot of running to every part of the world in some undescript amount of time, and unneccesary battles up until the last couple chapters - but I'm not holding my breath....
