I love Fantasy novels with a well worked out theory of magic, and Orphans of Chaos has one of the best I have read in a long time. Five students at a boarding school are kept in the dark about their past and their powers. Each student has a unique way of manipulating the forces of chaos. The main character is able to perceive higher dimensions and manipulate matter on a level invisible to others. Each student's abilities trumps that of another student but are in turn trumped by a different student. I was fascinated by how Wright worked out this system and incorporated it into a narrative connected to the Titans of Greek mythology.
On the downside, Wright has a rather sexist way of writing the female characters. I found this annoying and kind of intrusive, but not bad enough that it affected my enjoyment of the plot and background elements.
