Laughing Wolf

It is 2213 and a mysterious plague has broken out. Scientists can't stop its advance, and humanity is suddenly poised on the brink of eradication. The only possible cure is Lupus Ridens, or Laughing Wolf, a flower once common in ancient Rome but extinct for more than 2,000 years. Fifteen-year-old Felix Taylor, the last person on Earth who can speak and read Latin, must project back to Roman times circa 71 BC and retrieve the flower.
