This review is for the entire "Impervious" series, rather than just this story.
A boy with exceptional power grows up. He was adopted when young, so we know nothing of his true parentage, but he appears to have tremendous strength, and is impervious to any weapon used on him. In addition, skin-to-skin contact allows him to see the misdeeds of others, an ability which can bring about much pain.
For plot, I give the series a B (7). It has a lot of promise, and is above average, but jumps at different paces throughout the trilogy. It also leaves much unexplained which a curious reader would want to know.
For technical quality, it gets an A+ (9). There were few errors spotted throughout the story.
For personal appeal, a B+ (more than 7, but not quite 8). Each portion of the trilogy is relatively short, with less than 10 chapters. Combined, they make a pleasantly lengthy read. The issue I have is that the characters lack development. They appear to be relatively one-dimensional, yet they could be much more.
