Book on was really well written, though it did have a few downfalls. The plot seemed to swayed on one subject. Though the main point of the story is about the Sphere, it's really about the delver and his sword.
A truly wonderful magical sword that, though made by one species, awakens to it's full potential in another, giving him god like powers of premonition at times, and at others leaving me the reader grasping for understanding at to what is going on.
I truly enjoyed reading the first book and am looking forward to reading books two and three soon.
It's worth the time it takes to read it, couldn't put it down, and had a blast even though it had some decent sized plot holes.
