A YA/Adult Sci-fi book, set in the post-apocalyptic future of about 250 years, it's about a world lead by a strictly controlled world court, and a few powerful syndicates. After the bombs dropped some genetic code was altered, allowing for "psions," a group of people with powers, like telekinesis, empathy, telepathy, pyrokinesis, etc. There are two groups at odds with each other, and one rogue psion, who might be the most powerful of all. Part of a set I believe. Very entertaining, and she had some great battles between the psions. Lots of twists and turns and backstabbing, etc.
