Tessa Theus was a heroine: Thunder Girl. The greatest heroine, probably. Even with her questionable look and her all-around not-so-heroic attitude. Two years ago, she fought Saturn, the almighty Father of Manifest, and lost. Badly. But it seems that her fight is still not over, and even if she’s powerless and her memory is almost gone, Tessa has no other choice but to find – again! – her place on Manifest.
