Sci-Fi & Fantasy

Another day, another dollar, they said - but for Clarisse Evans, doctor and hucow extraordinaire, that old adage didn't apply at all. She hadn't been feeling at all extraordinary lately either - just kind of...rumpled? If that was the proper word. She had managed to stabilize the serum a bit - she would be the last hucow who had to suffer the curse of overpr...
