From publisher blurb:
Did Someone Say Paradox?
Cord (PL 10) is a demigod, a universe-saver, a Ultra-class meta, a cyborg, and a world fighting championship master. She may be the most powerful being in the universe, but she does not, and cannot, exist for any great length of time. She’s not real, but para-real. She only comes into existence when entire alternate realities are at stake.
Cord is the ultimate hero ... and the ultimate illusion. She is never alone, and exists only when she is needed. And then she fades away. Until next time.
